You're answer should be non of them if my math is right, but it usually is!
hope this helped!!! ;)
The A, the C and the D because we have the vectors YX and YW which start from Y and the angle XYZ because the angle is around Y
A^2-64=0 you can factor like this:
(a+8)(a-8)=0 and since a>0, a must be 8
or you can do this:
add 64 to both sides of the equation leaving you with:
a^2=64 taking the square root of both sides
a=(-8,+8) and since a>0, a=8
Answer:
B. Brand A $0.21
Step-by-step explanation:
(round to nearest cent)
Brand A: 21.99/105 = .2094 = .21 ( .2094 rounds to .21)
Brand B: 17.99/80 = .2248 = .22 ( .2248 rounds to .22)
Therefore Brand A is a better buy for $0.21 per load
