1.Simplify.
-2{x}^{2}-4x+13+12{x}^{2}+2x-25−2x2−4x+13+12x2+2x−25
2.Collect like terms.
(-2{x}^{2}+12{x}^{2})+(-4x+2x)+(13-25)(−2x2+12x2)+(−4x+2x)+(13−25)
3.Simplify.
10{x}^{2}-2x-1210x2−2x−12
Answer:
1) b
2)d
3)a
Step-by-step explanation:
1) count the number of different betwwen 2 cycles
2) take 5/160 time 8
3) take 12/9.6 then times 6.4
Convert 7/11 to a decimal value.
7 divided by 11 = 0.636364
Subtract 0.636364 to 0.757576 and divide the difference
by 2.
Following the equation, 0.636364 - 0.757576 =
0.121212.
<span>0.121212 divided by 2, the quotient is 0.06 (06
is repeating) </span>
