Answer 1

Answer:

A)15

Step-by-step explanation:

to understand this

you need to know about:

• equation
• PEMDAS

let's solve:

parimeter of a square:4a

according to the question

$\sf 4(8x + 2) = 488$

divide both sides by 4:

$\sf \frac{4(8x + 2) }{2}= \frac{488}{2} \\ \sf \frac{ \cancel4 ^{} (8x + 2)}{ \cancel{4}} = \frac{ \cancel{488} \: ^{122} }{ \cancel{ \: 2}} \\ 8x + 2 = 122$

cancel 2 from both sides:

$\sf 8x + 2 - 2 = 122 - 2 \\ \sf 8x = 120$

divide both sides by 8

$\sf\frac{8x}{8} = \frac{120}{8} \\ \sf \therefore \: x = 15$
