Answer:
990, C
Step-by-step explanation:
The formula for the surface area of the bottom cushion is
A = 2wl + 2lh + 2hw (w is width, l is length, h is height)
w = 18, l = 21, h = 3
A = 2(18)(21) + 2(21)(3) + 2(3)(18)
A = 2(378) + 2(63) + 2(54)
A = 756 + 126 + 108
A = 990 (C)
Answer:343
Step-by-step explanation:
The useful property in multiplication is that 1 raised to any number will always be equal to 1. Thus, if y is equal to 1, m and n are also equal to 1. But if y is greater than 1, then m and n would also, consequently, be greater than 1 but less than y. This is because the base number of an exponent must be less in value than the answer. However, if m and n are multiplied, then the product would be greater than 1 but still less than y.
Let's take an example to prove this point.
Suppose y=5, then
m = ⁴√5 = 1.49
n = ∛5 = 1.7
Then, m×n = 2.5 which is less than y but greater than 1
Answer:
the answer would be 5.

Answer:
x ≤ -5
Step-by-step explanation:
4x-2 ≤-22
Add 2 to each side
4x-2+2 ≤-22+2
4x ≤ -20
Divide each side by 4
4x/4 ≤ -20/4
x ≤ -5
