1. the kahn's family lives in a house that has a backyard in the shape of an isosceles trapezoid and a triangle. the area of the backyard can be expressed as the sum of the area of the triangle and the area of the trapezoid, which is bh+(pq the base and the height of the triangle are represented by b and h, respectively. the bases of the trapezoid are p and q, and the height of the trapezoid is l. 2 rearrange the formula to find the length of base as a function of the lengths of the other sections of the backyard.

Step-by-step explanation:

Given : The Kahn's Family lives in a house that has a backyard in the shape of an isosceles trapezoid and a triangle.

The area (A) of the backyard can be expressed as the sum of the area of the triangle and the area of the trapezoid :

, where base and the height of the triangle are represented by b and h, respectively. The bases of the trapezoid are p and q, and the height of the trapezoid is L.

To find the formula for base b, we subtract expression from both sides of the given formula , we get

Now, multiply both sides by 2 and divide both sides by h , we get

i.e. The formula to find the length of base as a function of the lengths of the other sections of the backyard will be :-

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.
