Answer:
12 and 3
Step-by-step explanation:
Let x= length
If you draw a rectangle. two sides would be the length x. The other two sides would be (x-9).
(length)(width) = Area
(x)(x-9) = 36
x^2 - 9x = 36 Substitute in x and x-9 for the length and width
x^2 - 9x - 36 =0 Subtract 36 from both sides
(x-12)(x+3) = 0 We are looking for 2 number that add to -9 and mult. to -36
x-12=0 and x+3=0 Set both factors to 0 and solve
x = 12 and x =-3. It does not make sense that a length could be -3 so we reject that answer. If the length is 12, then the width is 3
STEP 1: ADD ALL OF THE NUMBERS TOGETHER.
STEP 2: DIVIDE THE TOTAL BY THE AMOUNT OF NUMBERS SHOWN
THIS IS THE ANSWER

Answer:
Option four, 6b + 4r
Step-by-step explanation:
So the two mini-type equations are joined together with a plus. Which means the parenthesis don't do anything in this particular equation. You simply add all of the same variables together. (r's go w/ r's, b's go w/ b's)
(2b + 3r) + (4b + r)
2b + 4b + 3r + r
6b + 4r
