There are 4 variables in the expression. The variables are: a,b,c and d.
8d^2 = variable d
2bc = variables b and c
10ab = variables a and b
Answer:
x = 12
Step-by-step explanation:
(6x-2) + 20 = 90
6x-2 = 70
6x = 72
72 / 6 = 12
x = 12
The answer to this is 8%.
<span>perpendicular slope :
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
y = -2x + b
2 = -4 +b
b = 6
y = -2x + 6
