4(3A - 4) = 56
first distribute 4
12A - 16 = 56
then add 16
12A = 72
finally, divide by 12
A = 6
Answer:

Step-by-step explanation:
The area of a rectangle is equal to
, where
is the length of the rectangle and
is the width of the rectangle. In a rectangle, opposite sides are equal.
Therefore, we can write the following system of equations:

Expand the first equation:

Substitute the second equation into the first (
):

Solving for
:

Answer:
The formula to find the area of a circle is pi times the radius squared (A = π r²).
Step-by-step explanation:
What grade you in and what unit lesson is this, I might be able to help you. I go to the same school.
Hey there!
4/7 + 5/6
≈ 24/42 + 35/42
≈ 24 + 36/ 42 - 0
≈ 59/42
≈ 1 17/42
Therefore, your answer is:
59/42 or 1 17/42
EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT.
Good luck on your assignment & enjoy your day!
