The answer is C. 14
35/5=7
7•2=14
For this problem you have to isolate the variable. To do this you must inverse the operations. Multiply 18 by 5, then divide by 12 to get your answer of 7.5
Can u explain it a little more clearly...
We Know, Area of Trapezium = (a+b)/2 * h
Where, a & b are parallel bases & h is height.
Here, we have a = 8, b = 18, h = 5
substitute them into the expression, as follows:
Area = (8+18)/2 * 5
A = 26/2 * 5
A = 13 * 5
A = 65
So, area would be 65 cm²
Hope this helps!
Answer:
x = 14
Step-by-step explanation:
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
x = 14
