Answer:

1. x=18, y=6\sqrt{10}

2. x=108, y=180

Step-by-step explanation:

The height of the right triangle drawn to the hypotenuse is the geometric mean of two segments of the hypotenuse (two legs' projections)

1. Use this property, so

CD^2=AD\cdot BD\\ \\6^2=2\cdot x\\ \\36=2x\\ \\x=18

Consider right triangle BCD. By the Pythagorean theorem,

BC^2=BD^2+CD^2\\ \\y^2=18^2+6^2\\ \\y^2=324+36\\ \\y^2=360\\ \\y=\sqrt{360}=6\sqrt{10}

2. Consider right triangleGM*. By the Pythagorean theorem,

G*^2=GM^2+M*^2\\ \\240^2=GM^2+192^2\\ \\GM^2=240^2-192^2=(240-192)(240+192)=48\cdot 432=144^2\\ \\GM=144

Use this property to find x:

GM^2=192\cdot x\\ \\144^2=192\cdot x\\ \\x=\dfrac{144^2}{192}=108

Consider right triangle GMCup. By the Pythagorean theorem,

y^2=x^2+GM^2\\ \\y^2=108^2+144^2\\ \\y^2=32,400\\ \\y=180

Linda and Juan went shopping. Linda spent $14 less than Juan. If we let y represent how much Juan spent, write an algebraic expr
algol13

Answer:

An Algebraic expression representing amount spent by Linda is y-14.

Step-by-step explanation:

Given:

Let the amount spent by Juan be 'y'

Now Given:

Linda spent $14 less than Juan.

We need to find an algebraic expression for how much Linda spent.

Solution;

It is given that Linda spent $14 less than Juan.

So we can say that Amount spent by Linda will be equal to amount spent by Juan minus 14.

framing in equation for we get;

Amount spent by Linda = y-14

Hence An Algebraic expression representing amount spent by Linda is y-14.
