(6x^2 + 34x + 25)/(x+5)
Answer:
divided: 6x+4+(5)/(x+5)
the remainder: 5
I like to use long division to work these problems:
6x + 4
(x+5) ║ (6x² + 34x + 25)
- (6x + 30x) ↓
4x + 25
- (4 x + 20)
5
(6x^2 + 34x + 25)/(x+5) = 6x + 4 with a remainder of 5
⇒ (6x² + 34x + 25)/(x+5) = 6x + 4 + (⁵/ₓ ₊ ₅)What's 100 x 2000 x 2 x 1.45 x 5 x 7 x 78345 x 0?

*25 points* an someone pls tell me how many solutions this equation have
Answer:
infinite number of solutions
Step-by-step explanation:
4(z - 5) + 2 = 4z - 18 ← distribute and simplify left side
4z - 20 + 2 = 4z - 18
4z - 18 = 4z - 18 , which reduces to
0 = 0 ← a true statement
This indicates the equation has an infinite number of solutions
Evaluate 64^1/2x 10^-2
Give your answer as a fraction in its simplest form.
Answer:
your fraction is 32/100
Step-by-step explanation:
64^1=64 -> 64/2 = 32
10^-2= 0.01 -> 32 * 0.01 = 0.32 = 32 over 100
Sam is paid $50 per room that he paints and he can paint a room in exactly 2 hours. On sunday, sam hopes to make atleast $150 painting rooms and can work for exactly 10 hours. Which of the following sets represents the range of money (m) that sam can make without violating either his monetary or time restriction?
A. m= {150,250}
B. m={0,150}
C. m={0,250}
D. m={100,250}
Answer: A, {150,250}
Step-by-step explanation:
In 10 hours he can do 5x2 hours work. or 5x$50 = $250 for 5 rooms
$150 is 3x $50 or 3x2 hours work.
He can work 6 hours and make $150
or he can work 10 hours and make $250
the range he can earn so that he makes at least $150 and no more than 10 hours is$150 to $250
($150,$250) in interval notation for working 6 to 10 hours (6,10)

-x³-x²+5x-3 find each polynomial by degree and number of terms
Answer:
- (x-1)^2 x (x+3) is correct ans
Step-by-step explanation:
rewrite the expression
-x^3 - x^2 + 5x - 3
factor the expressions
x^3 + x^2 -2x^2 +2x=3x-3
factor the expression
-x^2 x (x-1)-2x x (x-1) +3 (x-1)
rewrite the expression
-(x-1) x (x^2 + 2x-3)
rewrite
-(x-1) x (x^2 + 3x - x - 3)
factor the expression
-(x-1) x (x^2+2x-3)
factor the expression
-(x-1) x (x x(x+3)-(x+3)
write in exponential form
-(x-1) x (x+3) x (x-1)
solution:
-(x-1)^2 x (x+3)

Three times a number increased by 44 is the same as the opposite of the number. Find the number
Answer:
- 11
Step-by-step explanation:
let the number be n then 3 times the number is 3n and the opposite is - n
3n + 44 = - n ( add n to both sides )
4n + 44 = 0 ( subtract 44 from both sides )
4n = - 44 ( divide both sides by 4 )
n = - 11
The required number is - 11

how would you prefer to see your quiz score,as a fraction or as a percent? Explain. (what would you choose and why?)
For me, a percent is easier to think about. Knowing I scored 80% make sense. 80%, like 80¢ out of a dollar, makes sense and I can relate to it.
If you tell me I scored 52/65, I can't relate to that as easily, even though that's still 80%.
Which one is this answer for this can someone help me pzl
Answer:
66
Step-by-step explanation:
The red mark with "22" indicted that's 22, So you can remove 44(A) and 66(D), It cant be 22(B), Its Cleary 11.5(C)

True or false: f(x) is a function.
0,5,10,15
0,1,2,3
Answer:
False.
Step-by-step explanation:
No f(x) is not a function because it is a one-to-many relation
Note that 5 maps to 1 and 3 so this is not a function.
the ratio of a shorter walkway to a longer walkway is 3 to 5. the lenght of the sorter walkway is 45 meters. what is the lenght of the longer walkway
Answer:
75 mStep-by-step explanation:
Let s- shorter walkway, l- longer walkway.
Given:
s/l = 3/5s = 45 mFind the length of l:
45/l = 3/5l = 45*5/3l = 75 mAnswer:
[tex]\sf\longmapsto \: length = 75 \: metres[/tex]
Step-by-step explanation:
Now let's find out what's the length of the long walkway–
[tex]\sf\longmapsto \: \frac{3}{5} = \frac{45}{\: length\: of \:longer\: walkway} [/tex]
[tex]\sf\longmapsto \: \: length\: of \:longer\: walkway= \frac{45 \times \: 5 }{3} [/tex]
[tex]\sf\longmapsto \: length\: of \:longer\: walkway= 75 \: metres[/tex]
The length of the longer walkway is [tex]\sf\longmapsto \: length = 75 \: metres[/tex]

A ⇒ 4, 5, 13B ⇒ 1, 2, 8, 11, 15C ⇒ 3, 6, 12D ⇒ 7, 9, 10, 14what is the square root of 46?
[tex] \sqrt{46} ≈6.78233[/tex]
It is not a perfect square root because the number we are getting is in decimal.The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle
Answer:
length = 12
width = 9
Step-by-step explanation:
Let w= width of rectangle
length = w + 3
2w + 2(w + 3) = 42
2w + 2w + 6 = 42
4w = 36
w = 9 ( width of rectangle)
width = 9 inches
length = 9 + 3 = 12 inches
Becky has 30 T-shirts in a drawer: 12 concert shirts, 8 team shirts, and 10 plain shirts. Of
the 10 shirts she randomly selects to give to charity, 3 are concert shirts. How does this
frequency compare to the expected frequency based on the probability of randomly
selecting a concert T-shirt?
Answer:
The chance of her selecting a Cocert shirt are 12/30 which means therw is more probability she would choose at least one and the least probability to choose a Team sirt since the odds are 8/30 so it is expected she would select 4 concert shirts not 3, at lest for me.
