Betsy uses 8.8 of blue paint and white paint to paint her bedroom walls. 1/4 of this amount is blue paint. And th rest is white

UNO [17]

Answer:

6.6 pints of white paint is used to paint the bedroom walls

Step-by-step explanation:

Pints of blue paint used to paint the bedroom walls = 8.8

Ratio of blue paint used = $\frac{1}{4}$

Therefore,

Ratio of white paint used = $1-\frac{1}{4}=\frac{3}{4}$

Pints of white paint used to paint the bedroom walls = $\frac{3}{4}(8.8)=3(2.2)=6.6$

Therefore,

6.6 pints of white paint is used to paint the bedroom walls.

Question 1 of 40<br> If f(x) = 4x² - 6 and g(x) = x² - 4x-8, find (f- g)(x).

Aleksandr-060686 [28]

Answer:

$\huge\boxed{\sf (f-g)(x) = 3x\² + 4x - 14}$

Step-by-step explanation:

<h3><u>Given functions:</u></h3>

f(x) = 4x² - 6
g(x) = x² - 4x - 8

<h3><u>Solution:</u></h3>

Subtract both functions

(f-g)(x) = 4x² - 6 - (x² - 4x - 8)

(f-g)(x) = 4x² - 6 - x² + 4x - 8

Combine like terms

(f-g)(x) = 4x² - x² + 4x - 6 - 8

(f-g)(x) = 3x² + 4x - 14
