Answer:

13.2''

Step-by-step explanation:

lets ? be x

x² + 15² = 20²

x² = 20² - 15²

x = √175

x = 13.2''

so missing length = 13.2''

If n represents a number then write an expression for two less than one fourth of n

Ne4ueva [31]

Answer: $\frac{1}{4}n-2$

This is the same as $\frac{n}{4} - 2$ and it is also equivalent to $0.25n-2$

=====================================================

Explanation:

n is some placeholder for a number

one fourth of that number is $\frac{1}{4}n$ which is the same as $\frac{n}{4}$ or $0.25n$ since 1/4 = 0.25

From here, we subtract off 2 to get $\frac{1}{4}n-2$ as one possible final answer.

The solutions to the inequalities are x >1 and x < 6

<h3>How to solve the inequalities?</h3>

The inequality expression is given as:

-2x + 5 < 3x + 10

Collect the like terms in the above inequality

-2x - 3x < 10 - 5

Evaluate the like terms

-5x < 5

Divide by -5

x >1

Also, we have

5(x - 2) <3x + 2

Open the bracket

5x - 10 < 3x + 2

Evaluate the like terms

2x < 12

Divide by 2

x < 6

Hence, the solutions to the inequalities are x >1 and x < 6
