It’s basically the same thing as -4=20 so your answer would be -5 or D
Answer:
<h2>S.A. = 234 mm²</h2>
Step-by-step explanation:
The formula of a surface area of a rectangular prism:
l - length
w - width
h - height
We have l = 15 mm, w = 3 mm, h = 4 mm. Substitute:
P = 2l + 2w
l = 2w
48 = 2(2w) + 2w
48 = 4w + 2w
48 = 6w
8 = w
l = 2w
l = 2(8)
l = 16
48 = 2(16) + 2(8)
48 = 32 + 16
48 = 48
Answer:
length = 16
width = 8
Answer: L ≈ 2.0 m
Step-by-step explanation:
Lsin40 = h
Lsin55 = h + 0.35
Lsin55 = Lsin40 + 0.35
Lsin55 - Lsin40 = 0.35
L(sin55 - sin40) = 0.35
L = 0.35 / (sin55 - sin40)
L = 1.98452 ≈ 2.0 m
