What is the answer I need help

SashulF [63]

Answer:

Step-by-step explanation:

There is a difference of 2 between consecutive odd integers.

let n , n + 2 and n + 4 be the 3 consecutive odd integers, then

n + n + 2 + n + 4 = 87 , that is

3n + 6 = 87 ( subtract 6 from both sides )

3n = 81 ( divide both sides by 3 )

n = 27, n + 2 = 27 + 2 = 29, n + 4 = 27 + 4 = 31

Thus

The 3 consecutive odd integers are 27, 29, 31 → B

Answer:

14. -5√30 +3√2

15. 18√5 -30√3

Step-by-step explanation:

You can multiply radicals using ...

(√a)(√b) = √(ab)

And you can simplify radicals using ...

√(a²b) = a√b

_____

14. Using the distributive property, then simplifying the radicals, we have ...

$\sqrt{3}(-5\sqrt{10}+\sqrt{6})\\\\=-5\sqrt{3\cdot10}+\sqrt{3\cdot6}\\\\=-5\sqrt{30}+\sqrt{3^2\cdot2}\\\\=\boxed{-5\sqrt{30}+3\sqrt{2}}$

15. Similarly, ...

$-2\sqrt{15}(-3\sqrt{3}+3\sqrt{5})\\\\=6\sqrt{15\cdot3}-6\sqrt{15\cdot5}\\\\=6\sqrt{3^2\cdot5}-6\sqrt{5^2\cdot3}\\\\=\boxed{18\sqrt{5}-30\sqrt{3}}$
