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
Step-by-step explanation:
the area of a parallelogram is
baseline × height
the height here is 4 cm.
the baseline is 12 - 2 = 10 cm
the area of the parallelogram is then
10 × 4 = 40 cm²
Answer:
3 1/2 gallons.
Step-by-step explanation:
1 6/16 + 2 1/8
= 3 + 6/16 + 1/8
= 3 + 3/8 + 1/8
= 3 4/8
= 3 1/2 gallons.
