Step-by-step explanation:
Answer:
x=18
Step-by-step explanation:
We need to find the areas of the rectangles
1st rectangle
A= l*w
A = (2x+4)*9
= 18x+36
2nd rectangle
A = l*w
= 15*(3x-30)
= 45x-450
Since the area of the rectangles are equal, we set these two equations equal
18x+36 = 45x-450
Subtract 18x from each side
18x-18x+36 = 45x-18x-450
36 = 27x-450
Add 450 to each side
36+450 =27x
486 = 27x
Divide by 27 on each side
486/27 = 27x/27
18=x
Answer:
15 minutes i think
Step-by-step explanation:
45÷6=7.5
meaning 7.5 minutes per girl
so 4 girls would be 30 minutes of work
so 45-30=15
Answer:
-21, -16, 4, 9
Step-by-step explanation:
-3: f(-3) = 5(-3)-6 = -15-6 = -21
-2: f(-2) = 5(-2)-6 = -10-6 = -16
2: f(2) = 5(2)-6 = 10 - 6 = 4
3: f(3) = 5(3)-6 = 15 - 6 = 9
