What is the value of the expression shown below? 8 + (7 + 1) ^2 ÷ 4 ⋅ 1 over 2 whole to the power of 4 (5 points)

(8 + [7+1] 2 ÷ 4 × 1) ÷ 2^4

Let's focus on what's in parentheses first.

8 + 8 × 2 ÷ 4 × 1

8 + 16 ÷ 4 × 1

8 + 4 × 1

8 + 4

12

Now, to what is outside the parentheses:

Because of the way it is written, you will do 12 ÷ 2 first.

12 ÷ 2^4

6^4

1296

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
