Answer:
4
Step-by-step explanation:
First, get x to one side.
subtract 6x to both sides
-8 = -2x
Then divide -2 to both side
If you use the equation for Rachel it would be
y=3x and for oliver it would be y=2x+5
Answer:
formula: 2πrh
Step-by-step explanation:
2πrh= 2×π×4×5≈125.66371
2w + 2l = 25
2 * 2 + 2l = 25
<em><u>Simplfiy.</u></em>
4 + 2l = 25
<em><u>Subtract 4 from both sides.</u></em>
2l = 21
<em><u>Divide both sides by 2.</u></em>
l = 10.5
Now that we have the value of l, we can find the area.
A = lw
A = 10.5 * 2
A = 21.
The length is 10.5cm.
The area of the rectangle is 21cm^2
