Gnom [1K]

They aren't equivalent

<h2>Explanation:</h2>

In order to determine whether the expression:

$(5x-20)-(4x-8)$

is equivalent to:

$x$

Genevieve needs to follow these steps:

Step 1. Get rid parentheses

$5x-20-4x+8$

Step 2. Combine like terms

$5x-4x-20+8$

Step 3. Solve

$x-12$

So:

$x\neq x-12$

Therefore, these two expressions aren't equivalent.

Ray Of Light [21]

Since C is 2mi east of A and 2mi south of B, the shortest distance from A to B would be a straight line which is equal to the hypotenuse of a right triangle with a base of 2mi and a height of 2mi..

d^2=x^2+y^2

d^2=2^2+2^2

d^2=4+4

d^2=2*4

d=√(2*4)

d=2√2 mi (exact)

d≈2.83 mi (to nearest hundredth of a mile)
