Answer:
19.) must add 9.02 to both sides the answer will be n= 12.87
20.) must subtract 31.53 from 62.4 but add a zero behind the 4 in the number 62.4 and the answer will be r=30.87
22.) Jake needs about 2.21 meters of wood to complete the school project.
Step-by-step explanation:
Your answer is 3.5 which is 3 1/2
Step-by-step explanation:
(f+g)(x) means f(x) + g(x).
(f−g)(x) means f(x) − g(x).
So all you have to do is add them and subtract them.
1. (f+g)(x) = f(x) + g(x)
(f+g)(x) = (3x − 7) + (2x − 4)
(f+g)(x) = 5x − 11
2. (f−g)(x) = f(x) − g(x)
(f−g)(x) = (3x − 7) − (2x − 4)
(f−g)(x) = 3x − 7 − 2x + 4
(f−g)(x) = x − 3
3. (f+g)(x) = f(x) + g(x)
(f+g)(x) = (2x + 3) + (x² + ½ x − 7)
(f+g)(x) = x² + 2½ x − 4
4. (f−g)(x) = f(x) − g(x)
(f−g)(x) = (2x + 3) − (x² + ½ x − 7)
(f−g)(x) = 2x + 3 − x² − ½ x + 7
(f−g)(x) = -x² + 1½ x + 10
Answer:
4 1/4
Step-by-step explanation:
This is the best expression or the best simplyfied version.
Answer:
V = 3579.6 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius = 10
The height is 11.4 and pi is 3.14
V = (3.14) * ( 10) ^2 * 11.4
V = 3579.6 ft^3
