Answer:
x³ + 11x² + 18x
Step-by-step explanation:
(x² + 2x)(x + 9)
Step 1: Distribute x²+2x into x + 9.
x³ + 2x² + 9x² + 18x
Step 2: Combine like terms.
x³ + 11x² + 18x
The area of this rectangle is x³ + 11x² + 18x.
Answer:
Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x
Step-by-step explanation:
The height is (x + 9) and the width is (x^2 + 2x) and the the area of the rectangle is equal to: Area= height x width = (x + 9) (x^2 + 2x) = x^3 + 2x^2 + 9x^2 + 18x = x^3 + 11 x^2 + 18x

Luisa is saving money to buy a new laptop computer that costs $460 . She started with $110 and every month she saves $25 . Her savings can be modeled by the function s (x) =25x+110
A : graph the equation below make sure you label each axis with the appropriate unit of measure
B. Write a statement using function notation that shows when Luisa will reach her goal
C: use words to describe the symbolic statement
Can you guys please help me I’ll mark you as a brainliest . Please help just this question please
Answer:
A: *Graph shown in image*
B: She will reach her goal when the x is 14 (14,460) with y being 460 (or the goal) giving you the equation [tex]y = \frac{50}{2} x + 110[/tex] going up 50 and going right 2 with x being 7 meaning you would have to go up 50 and right 2, seven times to reach 460.
Step-by-step explanation:
A: From your previous question you asked 14 hours ago with a screenshot, you did your graph wrong so for YOU make your graph look like the second image. (Plot the point 0,110 for the y intercept and plot -4.4,0 for the x line)
B: Lot's of explaining but you will get it once you add it to your own graph and go with the flow. Kind of like slope intercept form.
For C: you can answer in your own words since I gave you the priority answer(s)
In the given figure find out the value of x and y ?
Given info:
all sides are equal in the given triangle
It is an equilateral triangle all angles are equal and each angle is equal to 60°Given angles are 3y° and 2x°
→ 3y° = 2x° = 60°
→ 3y° = 60° and 2x° = 60°
→ y° = 60°/3 and x° = 60°/2
→ y° = 20° and x° = 30°
Therefore, x° = 30° and y° = 20°
Answer:-
The values of x = 30° and y = 20°
Key Knowledge:-
→ If all sides are equal in a triangle then it is an equilateral triangle
In an equilateral triangle,
→ all sides are equal.
→ all angles are equal.
→ all angles are equal to 60°

Drew and Danielle are sightseeing for the day. Between the two of them they take 118 pictures. If Drew takes 14 more than three times as many pictures as Danielle, how many pictures for each friend take?
Answer:
Drew = 92 pictures, Danielle = 26 pictures
Step-by-step explanation:
Amount of pictures Drew has = x
Amount of pictures Danielle has = y
First make a system of equations:
x + y = 118
x = 3y + 14
Then solve with substitution:
(3y + 14) + y = 118
4y = 104
y = 26
x + 26 = 118
x = 92

Answer:-3/4
Step-by-step explanation: Raises 3 units, goes to the left 4 units.
Answer:
-3/4
Step-by-step explanation:
Slope is rise over run. The line is negative as the line is falling, not rising. From one point to the next it falls 3, or rises -3. It runs 4, therefore the rise/run, or slope is -3/4.

a (x – 8)(x + 8)
b (x + 8)(x + 8)
c (x + 8)^2
d (x – 8)^2
Answer:
D. (x – 8)^2
Step-by-Step Explanation:
x2 - 16x + 64:
Step 1: Use the sum-product pattern.
[tex]x^{2} -16x+64\\x^{2} -8x-8x+64[/tex]
Step 2: Common factor from the two pairs.
[tex]x^{2} -8x-8x+64\\x(x-8)-8(x-8)[/tex]
Step 3: Rewrite in factored form.
[tex]x(x-8)-8(x-8)\\(x-8)(x-8)[/tex]
Step 4: Combine to a square.
[tex](x-8)(x-8)\\(x-8)^{2}[/tex]

a whole pizza is cut into twelfiths. if dexter eats 1/2 of the pizza and landry eats 1/3 of the pizza then what fraction of the pizza remains
Answer:
1/6
Step-by-step explanation:
Start be rewriting your fractions with a common denominator
Multiply [tex]\frac{1}{2}[/tex] by [tex]\frac{6}{6}[/tex] to get [tex]\frac{6}{12}[/tex]
Multiply [tex]\frac{1}{3}[/tex] by [tex]\frac{4}{4}[/tex] to get [tex]\frac{4}{12}[/tex]
These are the fractions of the pizza eaten in twelfths like the pizza is cut into.
Now subtract from [tex]\frac{12}{12}[/tex] which is the whole pizza to find the pizza remaining
[tex]\frac{12}{12} -\frac{6}{12}-\frac{4}{12} =\frac{12-6-4}{12} =\frac{2}{12} =\frac{1}{6}[/tex]

Bus X travels 40 miles per hour for 2 hours; Bus Y travels 60 miles per hour for 1 1/2 hours. What is the difference, in miles, between the number of miles traveled by Bus X and the number of miles traveled by Bus Y?
Answer:
it should be 250m
Step-by-step explanation:
Bus X travels 40m for 2h which gives you 80m and Bus Y travels 60m for 11/2h which gives you 330m so the difference in miles is 250m
Find the missing side of each triangle.
A) 10 cm
C) 17.1 cm
E) 5.8 cm
B) 11.4 cm
D) 13.8 cm
Answer:
The choice B) 11.4
Step-by-step explanation:
[tex] {x}^{2} + {(5.5)}^{2} = {(12.7)}^{2} \\ {x}^{2} + 30.25 = 161.29 \\ {x}^{2} = 13104 \\ x = 11.4[/tex]
By using Pythagoras theorem :
[tex] {x}^{2} = (12.7) {}^{2} - (5.5)x {}^{2} [/tex][tex] {x}^{2} = 161.29 - 30.25[/tex][tex] {x}^{2} =131.04[/tex][tex]x = \sqrt{131.04} [/tex][tex]x = 11.4[/tex]Correct choice is B
The slope of the line is 0. It passes through the point (-3,4). Identify two other points on the line. Justify you answer
Answer:
Two other points: (2, 4) (6, 4)
Step-by-step explanation:
A line with a slope = 0 is a horizontal line [with a y-intercept of (0, b)], given by the linear equation, y = 4. This means that the y-coordinate will always equal to 4, regardless of its corresponding x-coordinate. Basically, we could choose any x-coordinate to pair with the y-coordinate of 4.
I chose the ordered pairs, (2, 4) and (6, 4).
Attached is a screenshot of the graphed linear equation, y = 4.

RT is an altitude of Triangle QRSHi I’m suppose to write an equation and solve for it. I can’t figure out what I’m doing, it’s a straight angle. Thank you if you figure this out!
Answer:
Equation: 4x+28= 180
x= 38
Step-by-step explanation:
To solve, you should start by trying to find "x". To do this you can use the expression "4x+28= 180"
TO solve 4x+28= 180, first subtract 28 from both sides:
4x= 152
Then divide by 4;
x= 38
Check your work:
M<1= 38+10 -------> 48
M<2= 114+18 -------> 132
132+48= 180
Hope this helps!
