Hey
Area of first rectangle = 18 x 21 = 378 in^2
Area of second rectangle = 17 x 9 = 153 in^2
Total area = 378+153 = 531 in^2
Option 1
Hope this helps :)

Answer:
the answer is c because it's on the x axis is 1 and the y axis is on 4
To solve the average rate of change, use the formula of the slope:
m = ( y2 - y1 ) / ( x2 - x1 )
but first we must solve the value of the function when x = 3
f(3) = - log ( 4 * 3 ) + 5
f (3) = 3.92
solve the function when x = 8
f(8) = - log ( 4 * 8) + 5
f(8) = 3.49
so the average rate of change
m = ( 3.49 - 3.92 ) / ( 8 - 3)
m = - 0.09
The correct answer is Choice C.
Here are the steps to factor the expression:
30x^3 + 35x^2 + 10x
5x(6x^2 + 7x + 2)
5x(6x^2 + 3x + 4x + 2)
5x(3x(2x + 1) + 2(2x + 1))
5x(3x + 2)(2x + 1)
