Answer:
Step-by-step explanation: add the equations
2x² = 30
x² = 15
y² = 12 - 15
= -3
x4 -y4 = 15² - (-3)²
= 216
Answer:
116
Step-by-step explanation:
If we assume the quotient is px³+qx²+rx+s
Then the following must hold:
(px³+qx²+rx+s)(x+1) + 14 = x⁴ + ax² - 16
From this we can establish p,q,r and s and then a. Do the multiplication, and then find that:
p=1
p+q=0
q+r=a
r+s=0
s+14=-16
Combine these, and get:
s = -30
r = 30
q = -1
a = 29
Now that we have a, we can do a normal factorization:
(x⁴ + 29x² - 16) = (x³ + 2x² + 33x + 66)·(x-2) + 116
Answer: C. 242
Step-by-step explanation:
So first you need to know the formulas for the shapes (trapezoid and rectangle) to solve it.
Trapezoid- A= 1/2(b1+b2)h
Rectangle- L x W.
So to plug in numbers for trapezoid should look like: 1/2(13+24) (4)
1/2 (37) (4)
(18.5) (4)
=74.
For rectangle: 7 x 24= 168.
So add them together and you should have your answer. 168+74=242 in.
I hope this helped!!! :)
Answer: -3
The orgin is the point (0,0). To find the slope you can use rise over run. From (1,-3) you rise by 3 and run by -1. So, the slope of the line is 3/-1=-3.
