Answer:

Erica

Step-by-step explanation:

The given expression is 8x^2y+4xy.

The prime factorization of the first term is

8x^2y=2^3\cdot x^2\cdot y

The prime factorization of the second term is

4xy=2^2\cdot x\cdot y

The greatest common factor is product of the least powers of the common factors.

GCF=2^2\cdot x\cdot y=4xy

Therefore Erica  is correct.

Answer:

Step-by-step explanation:

7x +72 -12x = 52

-5x = -20

Find the surface area of the composite figure.
zhuklara [117]

Answer:

438.97 cm²

Step-by-step explanation:

To find the surface area, we break up the figure into two pieces(blue and yellow) and then add them together.

SA = 2(w · l + h · l + h · w)

2 · (6 · 16 + 4 · 16 + 4 · 6)

368 cm²

70.97 cm² + 368 cm²

438.97 cm²

A+5=5a+5 how do i do this problem
Natali5045456 [20]

Answer:

0 = a

Step-by-step explanation:

The first thing to do is subtract 5 from both sides.

a + 5 = 5a + 5

   - 5          - 5      

The 5's cancel out.

Now we have a + 0 = 5a

You next subtract the a from both sides.

a + 0 = 5a

-a          -a

0 = 4a

Lastly would to get a by itself so then we divide 4 from both sides

0 = 4a

_     _  

4     4

0 = a
