Answer:
A) x > -3
Step-by-step explanation:
277 units ^ 2.
once you solve for the area of each shape, you add them together, and you get 277 units ^ 2.
the area of both triangles are 24 units. we use the formula of a triangle to solve for this.
we don't know what the length is for the small rectangle, but we know that 6 plus 6 plus something else, equals 25. Which means that the missing side of the small rectangle is 13. you already know the height of the smaller rectangle, so you just multiply 13 * 8. that's the area for the small rectangle.
and for the large rectangle, we just multiply 25 * 5 which will give us 125. Now we all out of these area together and you get your solution.
