Answer:
1
Step-by-step explanation:
9x+5=4(x-2)+8
9x+5=4x-8+8
9x-4x=5
5x=5
x=1
-1
9x + 5 = 4(x - 2) + 8
9x + 5 = 4x - 8 + 8
5x + 5 = 0
5x = -5
x = -5/5
x = -1
I hope that is useful for you :)
45 = (b(4b - 2))/2
90 = 4b2 - 2b
4b2 - 2b - 90 = 0
(2b + 9)(2b - 10) = 0
2b + 9 = 0
2b = -9
b = -9/2
If we were looking for zeroes, this would be an answer, but since we're looking for measurement, we don't use negative numbers.
