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: FALSE
When you multiply an inequality by a negative number the inequality flips.
Answer:
area = 6x^2+10x-4 perimeter= 5x+3

Answer:
X<7. Graph 7. Then put a open circle and arrow it going left! And there you go.
Step-by-step explanation:
Add 18 to both sides. Since -2x has a negative, you flip the sign to less than instead of greater than.
