To show exponents, use the symbols button under the answer box or use ^ such as 4² or 4^2 to show 4 to the second power.
x³ + 2x² - 15x Find the LCD or the least common denominator; x
x(x² + 2x -15) is factored completely
Your answer is (7y-1) and (5x-8)
Answer:
16
Step-by-step explanation:
number = n
n/2 + 3 = n - 5
n/2 - n = -8
-n/2 = -8
n/2 = 8
n = 16
Answer:
r = 3 2/3
s = -0.444333
Step-by-step explanation:
Multiply the top equation by 2
14r - 6s = 52
2r - 6s = 8 Subtract the two equations
12r = 44 Divide by 12
r = 44/12
r = 3 8/12
r = 3 2/3
2r - 6s = 8
2*(2 2/3) - 6s = 8
2*2.6667 - 6s = 8
5.3334 - 6s = 8 Subtract 5.3334 from both sides.
- 6s = 2 2/3 Divide by - 6
s = - 0.4443333
