Answer:
2
Step-by-step explanation:
Answer:
119 square centimeters.
Step-by-step explanation:
Write the problem as an equation.
2(2x+3)+2x=48
Where x is width of the rectangle. 2x+3 represents the length.
4x+6+2x=48
6x+6=48
6x=42
x=7
The width is 7 cm. Then, find the length.
(2x+3) Given
(2)(7)+3 Plug in 7 for x
14+3
17
Then, find the area, width*length
17*7=119
Answer:
4, 22 See below
Step-by-step explanation:
2x + y = 30
5x + y = 42
Subtract the first from the second
3x = 12
x = 4 so socks cost $4
Put that into one of the original equations
2x + y = 30
2(4) + y = 30
8 + y = 30
y = 22 slippers cost $22
