ZanzabumX [31]
<span>Let y= original side So A = LW 60 = (y+15)(y-13) (y+15)(y-13) = 60 y^2 + 2y - 195 = 60 y^2 + 2y- 195 - 60 = 0 y = -17 or y= 15 Toss out the negative solution to get y= 15 as the only solution. So the square has a side length of 15 meters. The area of this square is 15^2 = 15*15 = 225 square meters.</span>

Solve and show how you did: -2x + (12 - 9) = 2 + 9 + 2x
Norma-Jean [14]
Remove parentheses
-2x + 12 - 9 = 2 + 9 + 2x

Simplify -2x + 12 -9 to -2x + 3
-2x + 3 = 2 + 9 + 2x

Simplify 2 + 9 + 2x to 2x + 11
-2x + 3 = 2x + 11

Add 2x to both sides
3 = 2x + 11 + 2x

Simplify 2x + 11 +2x to 4x + 11
3 = 4x + 11

Subtract 11 from both sides
3 - 11 = 4x

Simplify 3 - 11 to - 8
-8 = 4x

Divide both sides by 4
-8/4 = x

Simplify 8/4 to 2
-2 = x

Switch sides
x = -2

I rlly need help! im stuck on this! 20 pts
Vitek1552 [10]

Answer:

$960

Step-by-step explanation:

take the total salary to be 100%, since the taxes are 20% subtract 20% from 100% to get 80% which will represent the left over after the taxes have been taken so say if 100%=$1200 what about 80% 80times 1200 then divide by 100.

Hello there are 4 questions in this it will look like a lot but it is not and you don't have to answer all of it just look at th
alex41 [277]

Answer:

First one: x = 3, and y = 2

Second: 5

Third: Yes because he will have $37.50

Fourth: The numbers 2.5 and 3 will make it true

Step-by-step explanation:

1. 4(3) + 2(2) + 3 = 12 + 4 + 3 = 19

2. 4x + 2 = 22, 4x = 20, x = 5

3. 2.25y + 7.25z + 11.25, 2.25(2) + 7.25(3) + 11.25 = 4.5 + 21.75 + 11.25 = 37.5

He will get $37.50, which is enough.

4. The numbers 2.5 and 3 will make it true: 2(2.5) + 3 = 5 + 3 = 8, 2(3) + 3 = 6 + 3 = 9, the numbers below it won't make it true.
