Answer:

Solution: x ⩾ \frac{8}{5}

Step-by-step explanation:

x 3 + x 2 ≤ 10x – 8

Reorder the terms

3x + 2x ≤ 10x - 8

Collect like terms

5x ≤ 10x - 8

Move the variable to the left

5x -10x ≤ -8

Collect like terms

-5x ≤ - 8

Divide both sides

x ⩾ \frac{8}{5}

What is the percent of decrease from 40 to 22?
Vaselesa [24]

Answer:

45% decrease

Step-by-step explanation:

The formula for percent of decrease/ increase is

Original - change/ original

So 40 - 22 = 18

18/40 = 0.45

Turn 0.45 to percent by moving the decimal two spaces to the right

45%

You can check by multiplying the original number by the percentage. So,

40 x 0.45 = 18

Multiply. 3√2⋅2√8⋅√3⋅√6 <br><br> explanation would be lit
Delicious77 [7]

When two the same numbers under the square root multiply, they are equal to the value under the square root, for example √2⋅√2 = 2. So then we have:

3√2⋅2√8⋅√3⋅√6 = 3⋅√2⋅2⋅√(2⋅2⋅2)⋅√3⋅√(3⋅2) = 3⋅2⋅√2⋅√2⋅√2⋅√2⋅√2⋅√3⋅√3 = 3⋅2⋅2⋅√2⋅3 = 36⋅√2

or if the bolded 2 from above is also the square root, then the solution is:

3√(2⋅2)√(2⋅2⋅2)⋅√3⋅√(3⋅2) = 54
