I think that A. 12x+2y-6 is the answer, because 8+4 is 12 and -2+4 is 2 and there is nothing to combine with the 6.
Answer:
0.118 seconds
Step-by-step explanation:
This is a distance-rate-time problem, so we need to use the formula: d = rt, where d is the distance, r is the rate, and t is the time.
Here, the distance is actually the height, which is
metres. The rate is
metres per second. Plug in these values to find t:
d = rt
=
* t
Divide both sides by
:
t = 0.118 seconds
The answer is 0.118 seconds.
Center A : 375 per yr
Center B : 35 + 12(12) + 5(52) = 35 + 144 + 260 = 439 per yr
I multiplied 12 * 12 because it was $ 12 a month and there are 12 months in a yr. I multiplied 5 * 52 because each aerobic class is $ 5 per class, and she went once per week, and there are 52 weeks in a yr.
so the cheaper one is Center A
I can't tell the exact answer but there should be something given or there should be a similarity/congruency statement
Answer:
A
Step-by-step explanation:
(x-4)^2=5
(x-4)(x-4)=5
x(x-4)-4(x-4)=5
distribute
x^2-4x-4x+16=5
combine like terms
x^2-8x+16=5
move terms to the left and combine
x^2-8x+11=0
use the quadratic formula and simplify
x=-(-8)+/-2 to the square roots of 5 over 2
separate and solve
x=4+ square root of 5
x=4- square root of 5
ANSWER: x=4+/- square root of 5
