Answer:
B
Step-by-step explanation:
Given
11 - 4x = (3x - 2)² + 1 ← expand the squared factor using FOIL
11 - 4x = 9x² - 12x + 4 + 1, that is
11 - 4x = 9x² - 12x + 5 ( add 4x to both sides )
11 = 9x² - 8x + 5 ( subtract 11 from both sides )
0 = 9x² - 8x - 6 or
9x² - 8x - 6 = 0 → B
Sin = opposite / hypotenuse
cos = adjacent / hypotenuse
using pythagoras theorem =
adjacent = 5^2-3^2
= 16
= square root 16
=4
cos x = 4/5
Answer: 
Step-by-step explanation:
We know the rate for sales tax is:

This means Cindy has to pay for the bouquet of roses and the bouquet of daisies plus the
of the value of each item.
So, we have to calculate the sales tax for both items:

Hence:

Answer: 12.5%
Step-by-step explanation:
108-96=12, so he grew 12 inches.
12/96=0.125,
0.125*100=12.5, 12.5%
Sum would be equal to 720.
so, x-60 + x-40 + 130 + 120 + 110 + x-20 = 720
3x + 240 = 720
3x = 720 - 240
x = 480/3
x = 160
Angle F = x-20 = 160 - 20 = 140
In short, Your Answer would be 140
Hope this helps!
