Answer:
True
Step-by-step explanation:
Answer:
<u>L = 12 inches and W = 8 inches</u>
<u>Area = 96 in^2</u>
Step-by-step explanation:
Perimeter(P) = 2(width) + 2(length)
Let W = width and L = length
P = 2W + 2L
L = 2W - 4
Substitute: P = 2W + 2(2W - 4)
P = 6W - 8
P = 40 inches
40 = 6W - 8
6W = 48
W = 8
L = 2W - 4
L = 2(8) - 4
L = 12
<u>L = 12 inches and W = 8 inches</u>
<u>===============================</u>
Check to see if this works:
P = 2W + 2L
P = 2(12) + 2(8)
P = 24 + 16
P = 40 inches <u>YES</u>
<u>========</u>
Area = WxL
Area = (12)*(8)
<u>Area = 96 in^2</u>
Answer: 345.4
Step-by-step explanation:
SA=2πr^2+2πrh
SA=2(3.14)(5)^2+2(3.14)(5)(6)
SA=2(3.14)(25)+2(3.14)(30)
SA=2(78.5)+2(94.2)
SA=157+188.4
SA=345.4
Answer:
15 questions correct
15/20 = 75%
each 5 questions is 25 percent of the 100% so 3 x 5 = 15 = 75%
