The perimeter of a square is 32 cm what is the length of a diagonal
Dafna1 [17]
First you should draw yourself a square.Since you know it is a square you can find each side by dividing it by 4. 32/4 = 8. Since it is a square you know that both the length and width are 8. If you draw in the diagonal that is a right triangle. Use the Pythagorean theorem a^2 + b^2= c^2  to find the length of the diagonal. 
8^2  + 8^2 = c^2

2X+15= -3x how do you work this equation​
Sphinxa [80]

Answer: x=-3

<u>Add 3x to both sides</u>

<u></u>2x+15+3x=-3x+3x\\5x+15=0<u></u>

<u></u>

<u>Subtract 15 from both sides</u>

<u></u>5x+15-15=0-15\\5x=-15<u></u>

<u></u>

<u>Divide both sides by 5</u>

<u></u>5x/5=-15/5\\x=-3<u></u>
