Answer:
B
Step-by-step explanation:
In 45 45 90 triangles the ratio is a:a:a root 2 so the answer would be 3root 2/2 or c because when multiplied again by root 2 it will get you 3.
This is false.
The f(3x) means you are multiplying the input 'x' by 3 before plugging into the equation.
3f(x) means you are going to multiply your answer (output) by 3 after you've plugged the input value in and gotten the output.
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
Answer:
-4x^2-28x
Step-by-step explanation:
Distribute
-4x(x) and -4x(-7)
-4x^2 and -28x
