Answer:
![36\sqrt{2}+30\sqrt{3}+10\sqrt{14}+8\sqrt{21}](https://tex.z-dn.net/?f=36%5Csqrt%7B2%7D%2B30%5Csqrt%7B3%7D%2B10%5Csqrt%7B14%7D%2B8%5Csqrt%7B21%7D)
Step-by-step explanation:
Use the distributive property and the rules of roots.
![(2\sqrt{7}+3\sqrt{6})(5\sqrt{2}+4\sqrt{3}) = 10\sqrt{14}+8\sqrt{21}+15\sqrt{12}+12\sqrt{18}\\\\=\boxed{36\sqrt{2}+30\sqrt{3}+10\sqrt{14}+8\sqrt{21}}](https://tex.z-dn.net/?f=%282%5Csqrt%7B7%7D%2B3%5Csqrt%7B6%7D%29%285%5Csqrt%7B2%7D%2B4%5Csqrt%7B3%7D%29%20%3D%2010%5Csqrt%7B14%7D%2B8%5Csqrt%7B21%7D%2B15%5Csqrt%7B12%7D%2B12%5Csqrt%7B18%7D%5C%5C%5C%5C%3D%5Cboxed%7B36%5Csqrt%7B2%7D%2B30%5Csqrt%7B3%7D%2B10%5Csqrt%7B14%7D%2B8%5Csqrt%7B21%7D%7D)

(a√b)(c√d) = (ac)√(bd)
√(a²b) = a√b
Answer:
Yes.
Step-by-step explanation:
Friend's answer is correct.
Answer:
40
Step-by-step explanation:
let the unknown be y (x is used as times(multiplication) )
(y-17)x-6=-138
add /-6 to both sides
y-17x-6/-6=-138/-6
y-17=23
make y independent/add 17 to both sides
y-17+17=23+17
y=40
or in an easier way
-138/-6 =23
23+17=40
simply reversing the question to get the answer
Well if its going to be going up the same every year then you just have to add $2000 every year until you get to 10 years well idk if im right
