Answer:
B. 7 inches
Step-by-step explanation:
The surface area of a cube is denoted by: A = 6s², where s is the side length.
Here, we know that A = 294 in², so plug this into the equation to solve for s:
A = 6s²
294 = 6s²
s² = 49
s = √49 = 7
The answer is thus B, 7 inches.
Answer:
1 gallon
Step-by-step explanation:
1 gallon because they are sharing the equally
Call the width ' W '.
Then the length is W + 55
Perimeter (distance all around) = W + (W+55) + W + (W+55) = 4W + 110
4W + 110 = 1,310
4W = 1,200
W = 300-ft
Length = W + 55 = 355-ft
Well, it would end up to 3x=14 which is x=4.33
<span>Kent has a collection of pennies and nickles with a value of $1.98. The number of pennies he has is five less than twice the number of nickles. How many of each coin does Kent have?
----
p + 5n = 198
p = 2n - 5
</span>---
Sub for p
2n-5 + 5n = 198
