Answer:
x would equal -11 or 13
Step-by-step Explanation:
x(x - 2) - 143 = 0
x^2 - 2x - 143 = 0
-2x + x^2 = 143
-143 + (-2x) + x^2 = 0
(x - 13)(x + 11)
x - 13 = 0
Add 13 to both sides
x = 13
x + 11 = 0
Subtract 11 from both sides
x = -11
If you would like to solve a^(-5)b^(-4) / a^(-13)b^8, you can do this using the following steps:
a^(-5)b^(-4) / a^(-13)b^8 = a^13 / a^5b^4b^8 = a^8 / b^12
The correct result would be c. a^8 / b^12.
22, i think because 3 times 3= 9, and 9 times 3 minus 5= 22
First you need to add the prices to get 85.55. Then 100 - 85.55 is 14.45.
