Answer:
a) 12x + 22 b) 17 - x
Step-by-step explanation:
Perimeter is the sum of the each side length.
The first example is a rectangle so the (4x+8) and the (2x+3) are doubled.
(4x+8) x 2 = 8x+16
(2x+3) x 2 = 4x + 6
12x+22
(6 - 12x) + (2
+ x) + (9
+ 10x)
combine like-terms.
17 - x
Step by step explanation:
9+6x+5=0
Uses the "a", "b", and "c" from "a + bx + c", where "a", "b", and "c" are numbers
So in this case:
a would be 9
b would be 6
c would be 5
Then plug in from there..
Another way you can do it is using the square method.
