Answer:
A=400, L=2W, L*W=A so, L*W=400, so, 400=2W*W or 200=W*W or 200=
,
= W, L=2(
) and W=
, W=14.14 and L=28.28
Step-by-step explanation:
The equation is 4x-13 = 12
Multiply both sides by 3 to cancel out the 3 in the denominator of the left side of the equal sign. You get:
x + 4 = 18
Now subtract 4 from both sides to get variables one side, constants on the other.
x = 18 - 4
x = 14
Your answer is x = 14
Answer:
the answer is 13 hope that helps:)
