Step-by-step explanation:
this is your answer.........
The area of a trapezoid is calculated by the equation,
A = 0.5(b₁ + b₂)h
where b₁ and b₂ are the bases and h is the height. When we substitute the given expression for the dimensions in the given,
A = 0.5(4x + 2x)(x - 6)
A = 0.5(6x)(x - 6) = 3x² - 18
Thus, the answer is letter A.
Answer:
the answer is D
Step-by-step explanation:
Answer:
- Parallelogram has two pairs of parallel sides.
- Square has four right angles, two pairs of parallel sides, and all sides congruent.
- Trapezoid has only one pair of parallel sides.

Step-by-step explanation:
Carolyn's work is incorrect. Below is the correct solution:
Given:
----› Equation 1
-----› Equation 2
Substitute y = (x + 2) in equation 1
----› Equation 1
(substitution)
(distributive property)
[Note: this is where Carolyn made a mistake]

Collect like terms

(addition property of equality).

Substitute x = 11 in equation 2
-----› Equation 2
(substitution)
