Answer:
x = 18
Step-by-step explanation:
y = x + 8
2x + y = -10
Add 10 to 8, then subtract x from 2x leaving you with one x, and finally subtract y from y leaving you with X = 18
Answer:
7.1 m
Step-by-step explanation:
A cube has 6 congruent square faces.
Given the surface area = 302.46 m² then the area of one face is
302.46 ÷ 6 = 50.41 m²
The area of a square = s² ( s is the side length ), thus
s² = 50.41 ( take the square root of both sides )
s =
= 7.1 m
The length of each side of the cube is 7.1 m
Answer:
length: 5 yd
width: 4 yd
area: 20 yd^2
Step-by-step explanation:
1 yd = 3 ft
15 ft * (1 yd)/(3 ft) = 5 yd
12 ft * (1 yd)/(3 ft) = 4 yd
A = LW
A = 5 yd * 4 yd = 20 yd^2
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=132,−118
