Solve the inequality
(x+5)(x-1)^2(x-3)<0

-5 < x < 1 or 1 < x < 3

Step-by-step explanation:

First, you must solve the inequality. Using PEMDAS, you work from left to right save for the problem in the parentheses that has an inequality. Then you get x^4 − 18^2 + 32x − 15 < 0. Then, you factor the left side of the equation. you should put the factors equal to 0.

x − 1 = 0  

x − 1 = 0  

x − 3 = 0

x + 5 = 0

You find the x value and plug it into the original inequality. And, you should be able to find the numbers that work when inputted in the inequality.

the answer to question 1 is -8, 28.

step-by-step explanation:

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
