Answer:
480 Litres
Step-by-step explanation:
Percentage increase = 20% × 400
New value =
400 + Percentage increase =
400 + (20% × 400) =
400 + 20% × 400 =
(1 + 20%) × 400 =
(100% + 20%) × 400 =
120% × 400 =
120 ÷ 100 × 400 =
120 × 400 ÷ 100 =
48,000 ÷ 100 =
480
r + 4(r - 3)
<em><u>We'll use the distributive property to simplify this.</u></em>
r^2 - 3r + 4r - 12
<u><em>Combine like terms</em></u>
r^2 + r - 12 is the simplified form.
Answer:11
Step-by-step explanation: think about 5+6 then when you add 11 to the -5 you get 6.
remember that you have to do the same to both sides

minus 16 both sides



mulitply both sides by 4

![(x)(\frac{4]{4})>72](https://tex.z-dn.net/?f=%28x%29%28%5Cfrac%7B4%5D%7B4%7D%29%3E72)



343: 49 × 7 = 7^2 × 7 = 7^3
125: 25 × 5 = 5^2 × 5 = 5^3
x^12(7x+5)(49x^2 -35x + 25)
x^12(7x+5)(7x-5)^2
