Answer:
The factors of the polynomial are:
(x + 1) and (x - 3).
Step-by-step explanation:
Answer:
12 1/4
Step-by-step explanation:
(7 + X) × 8 - 4 × X = 56
7 + X × 8 - 4 × X = 56
7 + 8X - 4 × X = 56
7 + 8X - 4X = 56
7 + 4X = 56
4X = 56 - 7
X = 49/4
X = 12 1/4
2 1/2 is in mixed fraction. So let's first make it into improper fraction.
(2*2 + 1) / 2 = 5/2
5/2 of 7.25 = (5*7.25) / 2 = 18.125
in short, 18.125 is the answer
D 11 1/4
Step-by-step explanation:
3/4 + 1 1/2 is 2 1/4
2 1/4 x 5 is 11 1/4
Answer: 7 laps
Step-by-step explanation:
The athlete planned to run 3 miles
1 lap = 3/7 miles
x laps = 3 miles
by proportion :
x × 3/7miles = 3 miles
x = 3 ÷ 3/7
x = 3 x 7/3
x = 7
Therefore: the athlete will run 7 laps
