Answer: 49 in^2
Step-by-step explanation:
Trapezoid area formula = (a+b/2) x h
So...
(5+9/2) x 7
= 49 in^2
400 - 2 x Age = 244
-2*Age = -156
Age = 78 years
Answer:
A triangle is 180 degrees. Imagine that two angles would be given as maybe 89 and 30 degrees. With these two angles already given you can find the last third angle by adding the 2 given angles and subtracting it from 180. There fore it would look like 180-119=61. 61 would be your unknown angle degree.

Answer: 540
Step-by-step explanation:
To solve this expression, we use PEMDAS to solve it.
-9*-6= 54
54*10=540
Answer:
12
Step-by-step explanation:
The parallel sides must be the same length.
2x-6 = x+3
2x-x-6-3 = 0
x - 9 = 0
x = 9
x + 3 and 2x - 6 are both 12
