Solve this problem thanks

The three missing lengths are the left hypotenuse, x, the middle altitude, y, and the right hypotenuse, z.

9/y = y/16

y^2 = 9 * 16

y^2 = 144

y = 12

9^2 + 12^2 = x^2

x^2 = 225

x = 15

12^2 + 16^2 = z^2

z^2 = 400

z = 20

From left to right, the sides measure 15, 12, and 20 units.

Sphinxa [80]

<h3><em><u>Simplify -3y+2x-5y-7x is:</u></em></h3><h3>-8y - 5x</h3>

<em><u>Solution:</u></em>

<em><u>Given that, we have to simplify</u></em>

$-3y + 2x-5y-7x$

We can simplify the above expression by combining the like terms

Like terms are terms that has same variable ( with same exponent) with same or different coefficient

From given,

$-3y + 2x-5y-7x$

Here, like terms are -3y and -5y

And 2x and -7x

Group the like terms

$-3y-5y+2x-7x$

Combine the like terms

$-8y -5x$

Thus the given expression is simplified
