6a - (b - (3a - (2b + c + 4a - a - 2b + c)))
6a - (b - (3a - (2b - 2b + 4a - a + c + c)))
6a - (b - (3a - (3a + 2c)))
6a - (b - (3a - 3a - 3c))
6a - (b - 3a + 3a + 3c)
6a - (b + 3c)
6a - b - 3c

x³ + x² - 25x - 25
x²(x) + x²(1) - 25(x) - 25(1)
x²(x + 1) - 25(x + 1)
(x² - 25)(x + 1)
(x² - 5x + 5x - 25)(x + 1)
(x(x) - x(5) + 5(x) - 5(5))(x + 1)

zimovet [89]

Answer:   \bold{3\sqrt{2x}-36\sqrt x}

<u>Step-by-step explanation:</u>

7(3\sqrt{2x})-3(3\sqrt{16x})-3(3\sqrt{8x})\\\\=21\sqrt{2x}-9\sqrt{16x}-9\sqrt{8x}\\\\=21\sqrt{2x}-9\cdot 4\sqrt x-9\cdot 2\sqrt{2x}\\\\=21\sqrt{2x}-36\sqrt x-18\sqrt{2x}\\\\=(21-18)\sqrt{2x}-36\sqrt x\\\\=3\sqrt{2x}-36\sqrt x

mrs_skeptik [129]

Answer: 4 gallons require 5 5/39 spoons of syrup

Step-by-step explanation:

Given it takes 3 2/6 spoons to make 2 3/5 gallons of chocolate milk

i.e. 20/6 spoons make up 13/5 gallons of milk

⇒1 gallon require 20/6/13/5  spoons of milk

⇒ 20 x 5/6 x 13 spoons of milk

⇒ 100/78 spoons of milk

Therefore 4 gallons require 4 x 100/78 spoons

⇒ 400/78 spoons

⇒ 200/39 spoons

⇒ 5 5/39 spoons
