Im pretty sure the answer is C :)
Hello!
To find your answer you must subtract first:
70 - 21 = 49
Now, how much percent is 49 of 70?
49/70 = 0.7000
0.7000 * 100 = 70.00%
49 is 70% of 70.
I really hope this helped you! :)
To check your answer: (70 × 70.00)/100 = 49
Answer:
x=√-5
Step-by-step explanation:
8-3x=√(4x^2+20)+8
-8 -8
-3x^2=√(4x^2+20)^2
-3x^2=4x^2+20
-4x^2=20
divide both sides by -4
x^2=-5
√(x^2)=√-5
x=√-5
Sorry, I thought you meant what 1 minus three is, not questions 1 through three
