Answer:

The answer is 4a

Step-by-step explanation:

1) Simplify 4a² + 12a² to 16a².

$\sqrt{ {16a}^{2} }$

2) Use this rule:

$\sqrt{ab} = \sqrt{a} \sqrt{b}$

$\sqrt{16} \sqrt{ {a}^{2} }$

3) Since 4 × 4 is 16, the square root of 16 is 4.

$4 \sqrt{ {a}^{2} }$

4) Simplify.

$4a$

Therefor, the answer is 4a.

Find the smallest possible interger value n for which 99n is a multiple of 24

motikmotik

I would guess that you would need to find the Least Common Multiple (LCM) of 99 and 24 first.

After listing out all of the multiples, you would have 792 be the LCM of 99 and 24. But since we need to find the integer value of n, in 99n (which means 99 x n), then we need to divide 792 by 99, which would be 8.

n = 8

Find the slant height x of the pyramid shown, to the nearest tenth.

Elza [17]

Answer:

C. 6.9

Step-by-step explanation:

Pretend this is a 2-d diagram and use the Pythagorean theorem.

Pythagorean theorem: a^2 + b^2 = c^2

a = 6 mm

b = 7/2 = 3.5 mm

c = x

6^2 + 3.5^2 = x^2

36 + 12.25 = x^2

48.25 = x^2

$\sqrt{48.25} = \sqrt{x^2}$

x = 6.9
