Answer:
d and b and f
Step-by-step explanation:
Answer
given radicals
convert them into simplest radical form
a) √49
√49 = \sqrt{7\times 7}
= 7
b) ∛40
∛40 = ![\sqrt[3]{2\times 2\times 2\times 5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%5Ctimes%202%5Ctimes%202%5Ctimes%205%7D)
= 2 ∛5
c) √242
√49 = \sqrt{2\times 11\times 11}
= 11 √2
hence the number are converted into simplest radicals or rational form.
Infinitely many because if you take the top equation and multiply it by 2 you get the same equation. That means that any number you plug in for x is a solution
X = 33/8 and -3
Use the formula with a = 6, b = -7 and c = -75
Since we have the triangle, but don't know which side 4 is on, we have one where x is opposite a 50 degree angle (they are the same if across either 50 degree side) and another across the 80 degree one. In addition, it's really ratios and sin/cos/tan from there!
