Answer:
2
Step-by-step explanation:
For the image, you just multiply the numbers to find the sides
(4*2=8 5*2=10 3*2=6)
Then find out how you went from the preimage to the image.
4 * 2 = 8 etc.
Answer:
1.2
Step-by-step explanation:
15 ÷ 12.50 = 1.2
12.50(1.2)= 15
Answer: where is the question??

this is because when 40 is broken down into two numbers (one divisible to get out of the square root, and one not) you get 25 + 15 under the square root. we know that the square root of 25 is 5, so we can put 5 outside the root and leave 15 inside.

answer is for a) 
Answer:
Step-by-step explanation:
We have to organize the given polynomials from the least to greatest based on their degrees.
A). x + 2xyz
Here xyz = 
Power of x is = 1
Power of y = 1
and power of z = 1
So degree of (x + xyz) will be degree of the highest degree term = 1 + 1 + 1 = 3
B). 9x³y²
Degree of this term = power of x + power of y = 3 + 2 = 5
C). 18x²+ 5ab - 6y
Degree of the polynomial = Highest degree of the variable x = 2
D). 
Degree of highest degree term
= 4
So sequence of the polynomials based on their degrees will be
C - A - D - B [From lowest to highest]
