Given: Parallelogram length = 11 cm triangle atop the parallelogram :
short leg = 7 cm : Right triangle inside the parallelogram :
long leg = 9cmArea of parallelogram =
base * heightA = 11cm * 9cmA = 99 cm²
Area of a triangle atop the parallelogram: A = ab/2A = (11cm * 7cm)/2A = 77 cm² / 2A = 38.5 cm²
Total area of the figure 99 cm² + 38.5 cm² = 137.5 cm²
Answer:
in simplified form is 
Step-by-step explanation:
We need to solve the expression

We know that 
and 64 = 8*8
Solving we get

So
in simplified form is 
A car can travel 65 miles per hour.
Over 12 hours, it will travel 780 miles.

Answer:
-6
Step-by-step explanation:
Some nasty order of operations coming up.
Firstly, deal with that squared:
-12 / 3 * (-8 + 16 - 6) + 2
Simplify the bracket:
-12 / 3 * 2 + 2
Simplify -12 / 3:
-4 * 2 + 2
Simplify -4 * 2:
-8 + 2
Simplify:
-6
