Answer:
which triangle am confuse
Now, the nickels and dimes are at ratio of 3:2. However, the total amount is in dollars. So let's convert all amounts to pennies then.
$5.60 is just 560 pennies
3 dimes is just 30 pennies
2 nickels is just 10 pennies
so, the ratio from dimes to nickels is a ratio of 30:10 pennies, or 3:1 then, for a total amount of 560 pennies.
![\bf \cfrac{dimes}{nickels}\qquad 3:2\qquad\cfrac{\stackrel{pennies}{30}}{\stackrel{pennies}{10}}\implies \cfrac{30}{10}\implies \cfrac{3}{1}\implies 3:1~ratio \\\\\\ \cfrac{\stackrel{dimes}{pennies}}{\stackrel{nickels}{pennies}}\qquad 3:1\qquad \cfrac{3}{1}\implies \cfrac{3\cdot \frac{560}{3+1}}{1\cdot \frac{560}{3+1}}\implies \cfrac{3\cdot 140}{1\cdot 140}\implies \cfrac{420}{140}\\\\ -------------------------------](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7Bdimes%7D%7Bnickels%7D%5Cqquad%203%3A2%5Cqquad%5Ccfrac%7B%5Cstackrel%7Bpennies%7D%7B30%7D%7D%7B%5Cstackrel%7Bpennies%7D%7B10%7D%7D%5Cimplies%20%5Ccfrac%7B30%7D%7B10%7D%5Cimplies%20%5Ccfrac%7B3%7D%7B1%7D%5Cimplies%203%3A1~ratio%0A%5C%5C%5C%5C%5C%5C%0A%5Ccfrac%7B%5Cstackrel%7Bdimes%7D%7Bpennies%7D%7D%7B%5Cstackrel%7Bnickels%7D%7Bpennies%7D%7D%5Cqquad%203%3A1%5Cqquad%20%5Ccfrac%7B3%7D%7B1%7D%5Cimplies%20%5Ccfrac%7B3%5Ccdot%20%5Cfrac%7B560%7D%7B3%2B1%7D%7D%7B1%5Ccdot%20%5Cfrac%7B560%7D%7B3%2B1%7D%7D%5Cimplies%20%5Ccfrac%7B3%5Ccdot%20140%7D%7B1%5Ccdot%20140%7D%5Cimplies%20%5Ccfrac%7B420%7D%7B140%7D%5C%5C%5C%5C%0A-------------------------------)
Okay, so it basically means you're subtracting.
I'm going to give some examples of what the answer could be.
1. 5 - 5 = 0
2. 5 - 4 = 1
3. 5 - 3 = 2
4. 5 - 2 = 3
5. 5 - 1 = 4
6. 5 - 0 = 5
Or of course if you feel you would like to switch the order of the problems, go ahead and try that, but no matter what happens, make sure the addition version always equal 5, so just be careful :)
4b² + 8b + 3 = 0
4b² + 2b + 6b + 3 = 0
2b(2b + 1) + 3(2b + 1) = 0
(2b + 3)(2b + 1) = 0
b = -1/2 or b = -3/2
