It's the associative property. One way to remember the associative property is that the numbers don't change, but the location of the numbers change.
Answer:
The area would be 301 if x=5.
Step-by-step explanation:
Given expression is:
5x²+42x+16
We have to find the area when x=5
So putting x=5 in the given expression.
Area = 5(5)²+42(5)+16
Taking square of 5 and multiplying 42 by 5
Area = 5(25)+210+16
Area = 75+210+16
Adding all the terms
Area = 301
Hence,
The area would be 301 if x=5.
Formula:
Y=Mx+b
(Basically its like this: Y=Slope(x)+Y intercept)
The M will always be slope, and the b is always going to be the y intercept.
So, all you have to do now is find them.
<span>y=-4x-9</span>
y=-4(slope)x-9(y intercept)
So, -4 is the <em>slope</em>, and the <em>y intercept</em> is -9

Since we know that we can find area of a trapezoid by dividing our trapezoid into two triangles with parallel sides of trapezoid as bases of our triangles. The area of trapezoid is sum of the areas of these two triangles.
We have been given that areas of our triangles are and . We can find area of our trapezoid by adding areas of our both triangles.
Therefore, area of our trapezoid will be .
