60 because 2:4 is 1/2, and when you divide by a fraction, you multiply by the reciprocal (2/1 instead of 1/2) which would be 60 in this case.
Answer:
C & D
Step-by-step explanation:
x² + 3x - 3 = 0
a = co efficient of x² = 1
b= co efficient of x = 3
c = constant = -3
roots = (-b ± 
)/2a
= (-3±![\sqrt{3^{2}-4*1*[-3]}](https://tex.z-dn.net/?f=%5Csqrt%7B3%5E%7B2%7D-4%2A1%2A%5B-3%5D%7D)
)/2*1
= (-3±
)/2
= (-3±√21)/2
Since there are 12 inches in 1 foot you have to divide 84 by 12
84 divided by 12 is 7
So, there are 7 feet in 84 inches
The vertical angles made is ABE and CBD, Thus meaning that your answer is B
Ok....
