Answer:
A, B, D, F
Step-by-step explanation:
Given
f(x) = (x + 3)(x - 1)(x - 2)(x + 2)
To find the zeros let f(x) = 0, that is
(x + 3)(x - 1)(x - 2)(x + 2) = 0
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3 → B
x - 1 = 0 ⇒ x = 1 → F
x - 2 = 0 ⇒ x = 2 → D
x + 2 = 0 ⇒ x = - 2 → A
Answer:
Yes
Step-by-step explanation:
Lisa and Frank type at the same rate.
They both type 1 page every six minutes.
Lisa types 6 pages every 36 minutes, and if we divide the minutes by the pages, we get
And Frank types 5 pages ever 30 minutes, when we divide we get
Answer:
They are equal if that’s what you’re asking
Step-by-step explanation:
( 'x' is not 144 .)
The supplement of an angle is (180 - x) .
The problem says that (2/3) of 'x' is equal to (180 - x) .
180 - x = 2/3 x
Multiply each side by 3 :
( Note: 3 x 180 = 540 .)
540 - 3x = 2x
Add 3x to each side:
540 = 5x
Divide each side by 5 :
<u>x = 108°</u> .
