Answer:
114 units²
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, so
AB = CD , that is
13x - 7 = 5x + 9 ( subtract 5x from both sides )
8x - 7 = 9 ( add 7 to both sides )
8x = 16 ( divide both sides by 8 )
x = 2
Then
5x + 9 = 5(2) + 9 = 10 + 9 = 19
3x = 3(2) = 6
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height ), thus
A = 19 × 6 = 114 units²
Answer:
9 shirts
Step-by-step explanation:
12 - 6 = 6
6/2 = 3
3 times 3 = 9
Answer:
AnSum of two sides of triangle always greater than third side, so the possible values of h is:
7x-3x < h < 7x+3x
4x < h < 10x answer:
Step-by-step explanation:
Answer:
20ft^2
Step-by-step explanation:
The length is currently three feet, if you add two feet to three that makes five feet. Five times four is twenty.

Answer: The answer is (C) 180°.
Step-by-step explanation: Given that m∠A = 40°. ∠B is a complement of ∠A and ∠C is a supplement of ∠B. We are to find m∠B + m∠C.
Since ∠B is a complement of ∠A, so we have

Now, since ∠C is a supplement of ∠B, so we have

Therefore,

Thus, (C) is the correct answer.
