17) The measures of two sides of a triangle are (2x + 3y) and (5x – 2y). If the perimeter

elena-14-01-66 [18.8K]

Answer:

5x +4y

Step-by-step explanation:

The perimeter of a triangle is the sum of side lengths. That fact can be used to find z, the length of the third side.

(2x +3y) +(5x -2y) +z = 12x +5y . . . . sum of sides is perimeter

z = (12x +5y) -(7x +y) . . . . . . . . . . . . subtract (7x+y) from both sides

z = 5x +4y . . . . . . . . . collect terms; the length of the third side

The third side of the triangle is (5x +4y).

If m = (3x-1) and n = (3x+1),sjow that x² = mn+1 by 9

aalyn [17]

Step-by-step explanation:

${x}^{2} = \frac{mn + 1}{9}$

$(3x - 1)(3x + 1)$

$9 {x}^{2} - 1$

${x}^{2} = \frac{9 {x}^{2 } - 1 + 1 } {9}$

${x}^{2} = \frac{9 {x}^{2} }{9}$

${x}^{2} = {x}^{2}$

So this identity is true.

Julia bought stock at $281/8 per share. The value of each share increased by $65/8. How much is each share of stock now worth?

const2013 [10]

The worth of the share of stock is $ $34\frac{3}{4}$ .

<h3>What is the worth of the stock now?</h3>

A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.

A mixed fraction is a fraction that is made up of a whole number and a proper fraction. A proper fraction is a number where the numerator is less than the denominator.

The worth of the stock now = purchase price + increase in the share price

28 1/8 + 6 5/8

$34 \frac{1 + 5}{8}$

$34\frac{6}{8}$ = $34\frac{3}{4}$
