First simplify the equation and next multiply the 20 with the x^2 and find a number that adds together to give you the middle
2 feet = 24 inches
24 inches divided by 1 inch = 24
Answer is 24 pillows.
Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
50%, if you put it into a calculator 25/50 gives you .50, move decimal 2 times to the right to get 50.
