Answer:

v = -3

Step-by-step explanation:

1) Expand.

3v + 4v - 8 = -29

2) Simplify 3v + 4v - 8 to 7v - 8.

7v - 8 = -29

3) Add 8 to both sides.

7v = -29 + 8

4) Simplify -29 + 8 to -21.

7v = -21

5) Divide both sides by 7.

v = -21/7

6) Simplify 21/7 to 3.

v = -3

You’re given two side lengths of 3 centimeters and 5 centimeters. Which measurement can you use for the length of the third side

mrs_skeptik [129]

Answer:

You could use a measurement of 4 centimeters.

The valid range is 2 < x < 8 cms.

Step-by-step explanation:

The third side must either be less than 3+5, that is less than 8 cms and it must be greater than (5-3) = 2 cms. If it is any other length we could not construct a triangle.

A right triangle has leg measures of 8 and 15 inches. What is the area and perimeter of the triangle?

rewona [7]

Hello!

<h3><em><u>Answer</u></em></h3>

The area of the right triangle is 30 $in^{2}$ . The perimeter is 40 in.

<h3><em><u>Explanation</u></em></h3>

First, we must find the measure of the hypotenuse of the triangle by using the Pythagorean Theorem.

$a^{2}$ + $b^{2} = c^{2}$

$8^{2} + 15^{2} = c^{2}$

64 + 225 = $c^{2}$

√289 = $c^{2}$

17 = $c$

Now that we have all the side lengths, we can use the formulas to find the area and perimeter.

A = $\frac{bh}{2}$

A = (15 × 8) ÷ 2

A = 30

<h3>PERIMETER:</h3>

P = a + b + c

P = 8 + 15 + 17

P = 40
