Answer:
Step-by-step explanation:
8x² + 2(x²-1) = 8x² + 2*x² - 2*1
= 8x² + 2x² -2
= 10x² -2
Like terms: 8x² , 2x²
If we divide 56 by 4 we get 14. Why by4? So that one number is 3 times the other So he had 14 balls that went into the green bags and 42 (56-14) that went into the red bags. We could just answer the question and say 14 but I think they want to know how many in each green bag.
14 and 42 don't work because they are not the same number of balls. What number is a common factor? 7 is,
We could have 2 green bags and split the 14 balls into 2 groups of 7 and with the remaining 42 - put them into 6 red bags of 7 each.
And so the answer to your question is:
7 ball in each bag = 2 bags are green, and 6 bags are red
14 balls + 42 balls = 56 bouncy balls
Answer:
the answer is 89
Step-by-step explanation:
this is a hard one to salve but basically if you know and lern hout to do it it is not that hard
If you wanna solve for x, you have to try to get x by itself, right?
so,
<span>
tan36°= 12/x </span>
---> multiply both sides by x
<span>
xtan36 = 12 </span>
---> now, solve for x by dividing both sides by tan36
so, you need to do 12/tan36
<span>so when you plug that into your calc, you get: 16.5165... which rounds to 16.52
