The order of operations is PEMDAS. So it would be 8.4 +(13.1 - 0.6) = 8.4 + 12.5 = 20.9
Answer:
-40
Step-by-step explanation:
Multiply both sides by the reciprocal of 9/10 to get rid of the fraction
××y=-36 ×
y=-36×
y=
y=-40
Answer:
Factor x²−6x−27 using the AC method.
(x−9)(x+3)=0
If any individual factor on the left side of the equation is equal to 0 , the entire expression will be equal to 0.
x−9=0
x+3=0
Set x−9
equal to 0 and solve for x.
x=9
Set x+3 equal to 0 and solve for x.
x=−3
The final solution is all the values that make (x−9)(x+3)=0 true.
x=9,−3
