Answer:
Height h = 9 cm
Step-by-step explanation:
Given:
Surface area of cuboid = 102 cm²
Length l = 2 cm
Breadth b = 3 cm
Find:
Height h
Computation:
Surface area of cuboid = 2[lb + bh + hl]
102 = 2[(2)(3) + (3)(h) + (h)(2)]
51 = 6 + 3h + 2h
45 = 5h
Height h = 9 cm
Step-by-step explanation:
2(x + 10) = 3x - 30
2x + 20 = 3x - 30
2x - 3x = -30 - 20
-x = -50
x = 50°
Answer:
350 months
Step-by-step explanation:
200x + 2912 = 72912 subtract 2912 from both sides
200x= 70000
x= 350
A. 168 feet
b. 1 yard = 3 feet
168*3=504 so, 168 feet =504 yards
c. 504 yards*$15=7560
d. $7560
I’m pretty sure it’s 20 could be wrong
