Answer:
5x^2 + 20x
Step-by-step explanation:
5x(x+4)
5x*x + 5x*4
5x^2 + 20x
2/a= a/50
Cross multiply:
a* a= 2*50
⇒ a^2= 100
⇒ a= √100 or a= -√100
⇒ a= 10 or a= -10
Final answer: a= 10 or a= -10~
There are 2000 lbs in a ton.
2000/1 * 3/4= 6000/4 = 1500
Final answer: 1500 pounds
8x^3 + 1 = 0
8x^3 = -1 <----------- Step 1: Subtract 1 from both sides.
x^3 = -1/8 <----------- Step 2: Divide both sides by 8.
x = ∛(-1/8) <----------- Step 3: Cube root both sides
x = -0.5 <----------- This is the final answer when you plug the last step into the calculator
