Answer:

Solution:

→ 2x(x + 3)

Step-by-step explanation:

Method:

Grouping

→ Common factor

2x² + 6x
2(x² + 3x)

→ Rewrite in factored form

2(x² + 3x)
2x(x + 3)

To factorize something:

⇒ need to simplify the equation to its most basic form

Let's solve:

$2x^2+6x=2(x^2+3x)=2x(x+3)$

Thus the factorized form is ⇒ $2x(x+3)$

Answer: 2x(x+3)

Hope that helps!

Water flows at a rate of 8000 cubic inches per minute into a cylindrical tank. The tank has a diameter of 128 inches and a heigh

beks73 [17]

Answer:

The height of the water = 6.2 in. to the nearest tenth

Step-by-step explanation:

∵ The rate of flows of water into the tank = 8000 in.³/min.

∴ The volume of the water in the tank after 10 min. = 8000 × 10 = 80000 in.³

∵ The water take the shape of the tank

∴ The height of the water = volume of water ÷ Area of the base of the tank

∵ The tank is cylinder with diameter 128 in. and height 72 in.

∴ The area of the base of the tank = π(128/2)²

∴ The height of the water = $\frac{80000}{\pi(64)^{2}}=6.2169899$

∴ The height of the water = 6.2 in. to the nearest tenth

Answer:

-9

Step-by-step explanation:

$( \sqrt[4]{7} + 2)( \sqrt[4]{7} - 2)( \sqrt{7} + 4) \\ = ( { \sqrt[4]{7} }^{2} - {{2} }^{2} )( \sqrt{7} + 4) [because (a+b)(a-b) = a² - b²]\\ = ( \sqrt{7} - 4)( \sqrt{7} + 4) \\ = { \sqrt{7} }^{2} - {4}^{2}[because (a+b)(a-b) = a² - b²] \\ = 7 - 16 \\ = - 9$
