5x^2 + 42x + 16

what would the area be if x = 5

The area would be 301 if x=5.

Step-by-step explanation:

Given expression is:

5x²+42x+16

We have to find the area when x=5

So putting x=5 in the given expression.

Area = 5(5)²+42(5)+16

Taking square of 5 and multiplying 42 by 5

Area = 5(25)+210+16

Area = 75+210+16

Adding all the terms

Area = 301

Hence,

The area would be 301 if x=5.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

1/800 is the right answer
