Answer:
5. P = 23 m
A = 15 
6. P = 24.4 in
A = 15.3 
Step-by-step explanation:
Area formula of a triangle is A = 1/2 bh
Area formula of a parallelogram is A = bh
5. The height of a triangle is perpendicular to the base.
A = 1/2 * 10 * 3
A = 15 
6. The height of the parallelogram is also perpendicular to the base.
A = 9 * 1.7
A = 15.3 
Perimeter means you add all the side lengths.
5. The side lengths are 5m, 8m, and 10m. Adding those together, you get 23m.
6. A parallelogram has congruent opposite sides. That means your side lengths are 9 in, 3.2 in, 9 in and 3.2 in. Adding those together, you get 24.4 in.
88-38=50
50÷5=10
10×9=90
The answer is B
I'm pretty sure the answer is B) 11c+8.5(c-46)=470

Answer: Correct
Step-by-step explanation:
The conclusion is valid. Since
and
, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since
, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.
