factor the trinomial x²-11x+30?
Answer:
(x-5)(x-6)
Step-by-step explanation:
when we look at something like this we have a, b, and c
a=1 (in front of x)
b=-11
c=30
our goal is trying to find factors of c that will give us b so in this case factors of 30 that will give us -11
so when you list all the factors of 30 you find that 6 and 5 both equal 30 when multiplied and add up to 11
but... we need -11 so if we change the signs both to negative that will give us a -11 when added and also a positive 30 when multiplied (-6)(-5)
so we then write it as (x-6)(x-5)
and if you FOIL that out you will end up getting the original equation :)

Franco made a dozen muffins for his party. Upon taking them out of the oven, he noticed that 2 of the muffins were badly burned. Franco served 710 of the remaining muffins. Which equation shows the fraction of the non-burned muffins that remains? A. 1212−712=512 B. 1010−710=310 C. 1212−512=712 D. 1010−310=710
Answer:
10/10 - 7/10 = 3/10
Step-by-step explanation:
Muffins made = 12
Burnt muffins = 2
Good muffins = 12 - 2 = 10
Franco served 7/10 of the remaining muffins
Muffins served = 7/10 × 10
= 7
Muffins unserved = 10 - 7 = 3
Fraction of the non burned muffins remaining = non burned muffins - served muffins
= 10/10 - 7/10
= 3/10

find the value of x root (4/7)^2x-1=16/49
Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given expression:
[tex](\frac{4}{7}) ^{2x - 1}[/tex] = [tex]\frac{16}{49}[/tex]
Solve for x;
Solution:
16 = 4²
49 = 7²
So;
[tex](\frac{4}{7}) ^{2x - 1}[/tex] = [tex]\frac{4^{2} }{7^{2} }[/tex]
[tex](\frac{4}{7}) ^{2x - 1}[/tex] = [tex](\frac{4}{7} )^{2}[/tex]
Now;
2x - 1 = 2
2x = 3
x = [tex]\frac{3}{2}[/tex]
Jared wants to make a scale drawing of his bedroom. His bedroom is a rectangle with a length of 600 cm and width of 400 cm. He decided on a scale of 1 to 50. 1.Jared's bedroom door is 60 cm wide. How wide should the door be on the scale drawing? Explain how you know. 2.Jared's bed measures 4 cm by 5 cm on the scale drawing. What are the actual measurements of his bed?
Answer:
(1) 1.2 cm
(2) 200 cm by 250 cm
Step-by-step explanation:
The scaled dimention = (Actual dimension) x (scale factor) ...(i)
The given scale factor =1/50
(1) The actual width of the bedroom door= 60 cm.
So, from equation (i),
the width of the door on the scale drawing= 60 x (1/50)=1.2 cm
(2) The scaled dimension of the bed is 4 cm by 5cm.
So, the scaled width of the bed = 4cm and
the scaled length of the bed = 5cm.
So, from equation (i),
4 cm = (Actual width) x (1/50)
So, Actual width = 50 x 4 cm = 200 cm.
And, 4 cm = (Actual length) x (1/50)
So, Actual width = 50 x 5 cm = 250 cm.
=Hence, the actual measurements of his bed is 200 cm by 250 cm.
Which of the following shows finding the sum of 4 and -8?
Answer:
-4
Step-by-step explanation:
count by a number line and you will see
Answer:
the answer is -4
Step-by-step explanation:
First you have to determine which sign is bigger. The number 8 is greater than 4 so we have to use the negative sign. now we can subtract or add. eight minus or plus four is four or twelve. so if we add or subtract the negative sign and the number four together we will get negative four or twelve. This is how you get the sum for negative four and eight. Hope this helps!

What value of c makes the equation true?
let's solve your equation step-by - step
-3-3/4(c-4)=5/4
Step 1: simplify both sides of the equation.
-3-3/4(c-4)=5/4
-3+-3/4 c+3=5/4 (distribute)
(-3/4 c)+(-3+3)=5/4 (combine like terms)
-3/4c=5/4
-3/4 c =5/4
Step 2: Multiply both sides by 4/(-3)
(4/-3)*(-3/4 c)=(4/-3)*(5/4)
Answer:c=-5/3
Answer:

please help. find the measure of all missing angles.
Answer:
M1= 62 M2= 45 M3= 24
Step-by-step explanation:
For angle 1:
180-118 = 62
Angle 2:
180- (73+62)
Angle 3:
part 1
180-73= 107
part 2
180-(107+49)= 24
Answer:
Step-by-step explanation:
You have to solve for 1 before you do anything.
<1 + 118 = 180 The two left angles are supplementary
<1 +118-118=180-118
<1 = 62
Now you can go after angle 2
<1 + 73 + <2 = 180 All triangles have 180 degrees
62 + 73 + <2 = 180 Combine the left
135 + <2 = 180 Subtract 135 from both sides.
135-135+<2 = 180-135 Combine
<2 = 45
Angle 3 is a little trickier because the angle you need to find <3 is not labeled.
73 + x = 180
x = 180 - 73
x = 107
NOw you can find <3
107 + 49 + <3 = 180
156 + <3 = 180
<3 = 180 - 156
<3 = 24
I have left out the reasons for <3. Maybe you can supply them.

Answer:
-1
Step-by-step explanation:
The mean is the sum of all values divided by the amount of values.
We take the sum of all the numbers:
-3 + -8 + 12 + -15 + 9
-11 + 12 + -15 + 9
1 + -15 + 9
10 + -15
-5
We then divide the sum by how many number we have (we are given 5 numbers):
-5/5 = -1
Therefore, our mean is equal to -1.
Answer:
-1
Step-by-step explanation:
-3 + -8 + 12 + -15 + 9 = -5 Now divide it by the amount of numbers given. -5 / 5 = -1

What is the length of BC?
9 units
11 units
15 units
16 units
Answer:
x = 15
Step-by-step explanation:
I used the pythagorean theorem on BAC triangle
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below ;)
The length of BC is 15 units.
In the right triangle ABC.
we have AC = 8 units and AB = 17 units.
We need to find the length of BC using the Pythagorean theorem.
What is the Pythagorean theorem?It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.
In the given right-angle triangle ABC.
We have,
AB = hypotenuse and the other two sides are AC and BC.
Applying the Pythagorean theorem.
We get,
[tex]AB^{2} = AC^2 +BC^2[/tex]
Now substitute AC = 8 and AB = 17.
[tex]17^2=8^2+BC^2\\289=64+BC^2\\BC^2=289-64\\BC^2=225\\BC=\sqrt{225}\\ BC=15 ~units.[/tex]
Thus, we have the length of BC as 15 units.
