Answer:
16.7552
Step-by-step explanation:

30/360 x 3.142 x 8 x 8
= 16.7551 to four decimal places is
Answer:
63 cm^2
Step-by-step explanation:
p = l + w + l + w
32 = 2l + 2w
32 = 2(w + 2) + 2w
32 = 2w + 4 + 2w
32 = 4w + 4
28 = 4w
7 = w
l = w + 2
l = 7 + 2
l = 9
Check your work:
32 = 9 + 7 + 9 + 7
32 = 32
Correct
A = l × w
A = 9 × 7
A = 63
Answer:
3rd Option: -1(x + 15)
Step-by-step explanation:
When we factor our a negative 1, we take the opposite signs of what is given:
-1(x + 15)
To check, we simply just redistribute to check if it matches the original expression:
-x - 15
So the 3rd option is the correct choice.
