Answer:
13
Step-by-step explanation:
35% = .35
20 • .35 = 7
20 - 7 = 13
Formula for sufrace area of rectangular prisms: S= 2 (lw + lh + wh)
for the first prism, x=14, plug 14 into 2(x)--> 2(14)=28
7,8,28
S= 2 [7(8)+7(28)+8(28)]
S= 2 (28+196+224)
S= 2(448)
S= 896
for the second prism, x is just 14
7,8,14
S= 2 [7(8)+7(14)+8(14)]
S= 2 (28+98+112)
S= 2(238)
S= 476
Add the two sufrace areas we found and the answer will be
D) S= 1,372
Each cube has an edge length of 1/2 inch
V = 1/2 * 1/2 * 1/2
V = 1/8 cu in
There are 1120 of these cubes so the volume of the prism is 1/8 * 1120 = 140 cubic inches.
Answer:
B. -8
Step-by-step explanation:
6x = -51 +3
6x = -48
x = -8
Answer:
Step-by-step explanation
you are able to make two squares because you can use the square root of 36 and that twill give you 6 not a decimal.
in comparison if you do the square root of 15 it will give you 3.87298335
