Answer:

Total paint left over = \frac{13}{12}L

Step-by-step explanation:

Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint

             were mixed. In the end only 2/3 L of the mixture were used.

To find - How many liters of paint were left over ?

Proof -

Given that,

5/4 L of white paint and 1/2 L of blue paint were mixed.

So, total mixture = (\frac{5}{4} + \frac{1}{2})L

                          = \frac{5 + 2}{4}L

                          = \frac{7}{4}L

⇒Total mixture =  \frac{7}{4}L

Now,

Given that ,

In the end only 2/3 L of the mixture were used.

So, total mixture left = (\frac{7}{4} - \frac{2}{3})L

                                = \frac{21 - 8}{12}L

                                = \frac{13}{12}L

∴ we get

Total paint left over = \frac{13}{12}L

A square has an area of 9yd^2. What is the length of each side?
BlackZzzverrR [31]

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length.  Since we know the area, and we need to find the side length so we just need to find the square root of the area.

\sqrt{9} = 3    

The side length is 3 yards.

37-(-3)squared+30\(-3)x2
vampirchik [111]
Simplify: 
37 - (-3)^2  + 30/(-3)x^2
= 37 +  - 9 +  - 10x^2

Combine like terms:
= 37 +  - 9 +  - 10x^2
= ( - 10x^2) + (37 +   - 90
= - 10X^2 + 28
Answer: - 10x^2  +  28



To Factor: 
37 - (- 3)^2 + 30/- 3x^2

- 10x^2 + 28
- 2(5x^2 - 14)

Answer:  - 2(5x^2 - 14)




I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -





Hope that helps!!!!
