<h3>Answer: Choice A) x+14</h3>
=======================================
Work Shown:
(f-g)(x) = f(x) - g(x)
(f-g)(x) = (f(x)) - (g(x))
(f-g)(x) = (3x+10) - (2x-4)
(f-g)(x) = 3x+10 - 2x+4
(f-g)(x) = (3x-2x) + (10+4)
(f-g)(x) = x+14
286 is the sum of the series below. You can plug this in or use long addition.
Either that or you make an average and that's your answer.
Answer:
d=7/2
Step-by-step explanation:
3/4d-1/2=3/8+1/2d
multiply all by 8, to make them into whole numbers (makes it easier)
6d-4=3+4d
move terms
6-d-4d=2d
3+4=7
7=2d
d=7/2
Answer:
c = 8.7 inches
Step-by-step explanation:
a^2 + b^2 = c^2
Substitute in the known values for a and b (the order doesn't matter):
(4.8)^2 + (7.3)^2 = c^2
multiply 4.8 times itself, 7.3 times itself:
23.04 + 53.29 = c^2
76.33 = c^2
Now find the square root of both sides of the equation (square root of c^2 = c):
8.736= c
It says round to the nearest tenth, so c = 8.7 inches
