Hey i need help and Use mental math to solve the equation. x – 16 = 14

A. 30
B. 2
C. –2
D. –30
i think the answer is c

A. 30

Step-by-step explanation:

This is a common mistake when you often second guess yourself.  Since this is an algebra equation, you want to solve for the value of x and x alone since you are going to isolate the variable.  The only way to do this equation is to add 16 on both sides to get 30 which is your final answer.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
