1. x^2-18x+(18/2)^2=19+(18/2)^2

(x-18/2)^2=100

(x-9)^2=100

x1= -1 x2= 19

Answer:

7.5 Quarts

Step-by-step explanation:

D'Naisa mixed the following:

1 gallon of orange paint
2 quarts of yellow paint
3 pints of red paint.

We are to determine in total, the number of quarts of paint that she mixed. this is done by converting each of the volume to quart.

1 gallon of orange paint

1 gallon = 4 Quarts
Orange Paint=4 Quarts

3 pints of red paint.

1 pint =0.5 quart
3 Pints =3 X 0.5 Quart
=1.5 Quart of red paint

Therefore,

Total Volume of Paint Mixed in quart= Volume of Orange+Yellow+Red

=4+2+1.5

=7.5 Quarts

notka56 [123]

9w+45= amount of money she’ll have after any amount of weeks.

So, since W is weeks... and you have 9 weeks, you do (9x9)+45.

Then you get 81+45, which is 126. She will have $126 after 9 weeks

Simplify 2(5/3+3/4)-4/3 A) 13/12 B) 11/4 C) 3 D) 7/2

bixtya [17]

Hello there!

$2(5/3+3/4)-4/3$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

$2(\frac{5}{3}+\frac{3}{4})-\frac{4}{3}$

$2(\frac{5}{3}+\frac{3}{4})=\frac{29}{6}$

$\frac{29}{6}-\frac{4}{3}$

You had to used least common multiple of 6 and 3.

Prime factorization of 6: 1, 2, 3, 6

3*2=6

Prime factorization of 3: 1, 3

1*3=3

Then multiply by the number

3*2=6

You can also multiply by each numerator by the same amount needed to multiply its corresponding denominator to turn it into the least common multiple is 6.

Then you had to used 4/3 multiply by the denominator and numerator by 2.

$\frac{4}{3}=\frac{4*2}{3*2}=\frac{8}{6}$
