The sum is of n and 14 can be written as:
n+14=72
2(4x-1) + 3x = 8x - 2 + 3x
= 11x - 2
Hope this helps
Answer:
y = 8x + 50
Step-by-step explanation:
Use (0,50) and (10,130)
Slope: m = (130-50)/(10-0) = 8
Y-intercept is 50
y = 8x + 50

Answer:
±90
Step-by-step explanation:
√(-225) · √(-36) = (15i)·(6i) = 90i² = 90·(-1) = -90
_____
On the other hand, ...
... √(-225) · √(-36) = √((-225)·(-36)) = √8100 = 90
___
If you consider all the roots at each stage, the result is ±90. Since you're working with complex numbers here, it is reasonable to recognize every number has two square roots.
... √(-225) = ±15i
... √(-36) = ±6i
... √(-225) · √(-36) = (±15i)·(±6i) = ±90i² = ±90
