What is the area of the right trapezoid? Please answerrr
Vanyuwa [196]

Answer:

A = 56 in²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = \frac{1}{2} h (b₁ + b₂ )

h is the perpendicular height between bases and b₁, b₂ the bases

here h = 7 , b₁ = 10 , b₂ = 6 , then

A = \frac{1}{2} × 7 × (10 + 6) = 3.5 × 16 = 56 in²

What are the solutions of the system?
miskamm [114]
We have the following system of equations:
 y = -6x-6
 y = x2-5x-6
 Matching we have:
 x2-5x-6 = -6x-6
 Rewriting we have:
 x2-5x-6 + 6x + 6 = 0
 x2 + x = 0
 Rewriting:
 x (x + 1) = 0
 The solutions are:
 x = 0
 x = -1
 For x = 0
 y = -6 (0) -6 = 0-6 = -6
 y = -6
 For x = -1
 y = -6 (-1) -6 = 6-6 = 0
 y = 0
 The solutions are:
 (x, y) = (0, -6)
 (x, y) = (- 1, 0)
 Answer:
 
The solutions of the system are:
 (-1, 0) and (0, -6)
