The easiest way is to graph them—otherwise, set each equation equal to each other:
Answer: I think 2/15 again I THINK
No, the equation is not a linear equation.
There is the x^2 thing that doesn't make it a linear equation.
Let x be the multiplicative inverse, then:
-1/4 * x = 1
x = 1 / (-1/4)
= 1 * -4
96 m²2 (this is the last of the given possible answers).
Recognize that this figure is made up of a parallogram (on the left) and a triangle (on the right).
The length of the parallelogram is 10 m and the height 6 m. Thus, the area of this parallelogram is (10 m)(6 m) = 60 m².
The formula for the area of a triangle is A = (1/2)(base)(height). Here, the area is
A = (1/2)(12 m)(6 m) = 36 m²
The total area of the figure is the sum of the two subareas:
A = 60 m² + 36 m² = 96 m²
