We know that the original width was 5, and that after the enlargement the width is 45. To calculate the scale factor we divide the final width between the original one, then:
Therefore the scale factor is 9.
The function {(-1, 2), (-2, 1), (0, 2)} has the function rule y = x + 3. HELPPPPPP

Answer:
420
Step-by-step explanation:
The remainder theorem tells you the remainder is f(4), which you can find by evaluating the expression for x=4. Evaluation is simpler if the expression is written in Horner form first.
... f(x) = (((x +4)x -1)x -16)x -12
... f(4) = (((4 +4)4 -1)4 -16)4 -12
... = ((8·4 -1)4 -16)4 -12
... = (31·4 -16)4 -12
... = 108·4 -12 = 420

The intermediate results (contents of parentheses) are the same as the intermediate results you get when you use synthetic division.
