Answer:
B. 2x^2 -5x +2y
Step-by-step explanation:
Substitute the given expressions and collect terms.
g(x) -f(x)
= (2x^2 -3x +6y) -(2x +4y)
= 2x^2 -3x +6y -2x -4y
= 2x^2 -5x +2y . . . . . . . . . . matches choice B
Answer: 10 cm
Step-by-step explanation:
The circumference of the CD = 22\pi
We know that the formula of the circumference is:
Circumference = 2\pi r
We will substitute the value of circumference to find the radius:
22 pi = 2 x pi x r
r = 11
Therefore its radius will be 22 / 2 = 11 cm
Jamie wants to cut the CD from the middle of the CD to one side but leaving one cm. To find the measurement of the cut portion, we will subtract 1 from 11 to get:
11 - 1 = 10 cm
