What is the factor coefficient variable of 5c-15
2 answers:
To find the factor coefficient variable, you would divide the numbers by a number that could be divisible for both numbers. In the case, the number you going to be dividing with is 5.
When you divide, your equation would look like this:
When you divide the numbers by 5, you would end of up with 5(c-3).
Your answer would be 5(c-3).

Answer:
180
Step-by-step explanation:
For each of the two right triangles, by the Pythagorean theorem, she shared side is of length 15. So, the area of each of the top two rectangles is (½)(8)(15), so their combined area is 120.
Moving onto the trapezoid, we can use the formula for the area of a trapezoid to determine its area is (½)(14+16)(4)=60.
So, the answer is 120+60=180.
