Answer:
A) 14x + 2
Step-by-step explanation:
(2x + 2x) + (5x + 5x) + (1 + 1)
= 4x + 10x + 2
= 14x + 2
You can only add 4x and 10x since they both have a variable (x). You cannot add 2 since 2 doesn't have a variable, so the answer in simplest form is 14x + 2
7. m = -5/4
8. m = -3/2
9. m = 3
10. m = -1
11. m = 1/4
12. m = 1/3
There are 12 inches in a foot, so we can simply divide the amount of inches (100) by 12 to get the amount of feet.
100ipm/12
Hope this helps!
*ipm stands for inches per minute.
Answer:
x = 
Step-by-step explanation:
1. Move everything to one side of the equation.
x^2 - 19x - 1 = 0
2. Use the quadratic formula where a = 1, b = -19, and c = -1.
x = (-b +- sqrt(b^2-4ac)) / 2a
If you plug those numbers into that formula, you will get the result listed above
