9. If f(x) = 5x-4 and f(2a) =156 , then what is the value of a?

$f(x) = 5x - 4$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

$f(2a) = 5(2a) - 4$

$f(2a) = 10a - 4$

$156 = 10a - 4$

$10a - 4 = 156$

Add sides 4

$10a - 4 + 4 = 156 + 4$

$10a = 160$

Divide sides by 10

$\frac{10a}{10} = \frac{160}{10} \\$

$a = 16$

A square has an area of 49 cm^2

crimeas [40]

To find area you need to multiply
length x width

Since 49 can be square rooted it equals seven

L x W = Area
Area = 7 x 7
Area = 49

Meaning since it’s a square the perimeter is
7 by 7 by 7 by 7 in other words 7 + 7 + 7 + 7 OR 7 x 4(equal sides)
