Fractions that have the same number on the bottom have a "common denominator."
It is written in expanded form. In standard form, it could have been written as;
7.0×
Let's break it up into 2 figures, the rectangle on the right with dimensions 3 x 10, and the rectangle on the left with dimensions 8 x 6.
A = 3 x 10
A = 8 x 6
A = 30
A = 48
The sum of these two, 78, will represent the area of the total figure.
Bh + hr = 25
you can factor out an h from the left side of your equation:
h(b + r) = 25 ... divide both sides by h
b + r = (25/h) ... subtract r
b = (25/h) - r
