. If QS bisects angle PQR, m angle PQS = (7x - 6)° , and m angle SQR = (4x + 15)° , find m angle PQT.

Paul [167]

Answer:

Step-by-step explanation:

PQS = (7x - 6)°

SQR = (4x + 15)° since QS bisect PQR these two expressions must be equal

7x - 6 = 4x + 15 transfer like terms to the same side of the equation

7x - 4x = 15 + 6

3x = 21 divide both sides by 3

x = 7

also the sum of these two would give us the measure of PQR

7x + 4x + 15 - 6 = PQR

11x + 9 = PQR replace x with 7

11*7 + 9 = 86 this is the measure of angle PQR and also supplementary to PQT so the measure of PQT = 180 - 86

Some rectangles have an area of 36 cm². Let the variable W represent the width of these rectangles. Which expression represents

ZanzabumX [31]

Answer:

The perimeter of the rectangle is expressed as; $P = \frac{72 \ + \ 2W^2}{W}$

Step-by-step explanation:

Given;

area of the rectangle, A = 36 cm²

width of the rectangle, = W

Let L represent the length of the rectangle,

A = L x W

$L = \frac{A}{W} = \frac{36}{W}$

The perimeter of the rectangle is calculated as;

P = 2(L + W)

Substitute the value of L into the above equation;

$P = 2(L + W)\\\\P = 2 (\frac{36}{W} + W)\\\\P = 2 (\frac{36 + W^2}{W} )\\\\P = \frac{72 \ + \ 2W^2}{W}$

Thus, the perimeter of the rectangle is expressed as $P = \frac{72 \ + \ 2W^2}{W}$
