Solve 4(x + 2) = 20

KiRa [710]

Answer:

x = 3

Explanation:

$\sf 4(x + 2) = 20$

$\sf 4x + 8 = 20$

$\sf 4x = 20 - 8$

$\sf 4x = 12$

$\sf x = \frac{12}{4}$

$\sf x = 3$

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3

sesenic [268]

Answer:

The correct option is D.

Step-by-step explanation:

The given expression is

$(4-\sqrt{7})(4+\sqrt{7})$

Difference of two squares property:

$a^2-b^2=(a+b)(a-b)$

Using the above property, the given expression can be written as

$(4)^2-(\sqrt{7})^2$

Applying square we get

$16-7$

$9$

Therefore the correct option is D.
