Answer:
4 + 10x^2
Step-by-step explanation:
–2 (–2 – 5x^2)
Distribute
-2 *-2 -2*-5x^2
4 + 10x^2
Answer:
3x2+15x=18
Step 1: Subtract 18 from both sides.
3x2+15x−18=18−18
3x2+15x−18=0
Step 2: Factor left side of equation.
3(x−1)(x+6)=0
Step 3: Set factors equal to 0.
x−1=0 or x+6=0
x=1 or x=−6
Answer:
-0.4
Step-by-step explanation:
Because some of the work input is turned into waste byproducts like heat. A simple machine has friction to overcome, and by doing that heat is created
