Answer:
B.
Step-by-step explanation:
For an expression to be a polynomial , it must contain no square roots of variables, no fractional or negative powers on the variables, and no variables in the denominators of any fractions.
(a) You can plant 7 1/4 acres per pound of seed
(b) Isabel takes 7 minutes to run a mile
So using the equation distance = velocity * time
we get distance/velocity = time
60 MPH: 290/60 = 4.83333 Hours
60 MPH: 290/70 = 4.1429 Hours
Difference between them:
4.8333 - 4.1429 = 0.69 Hours, then multiply that by 60 and you get
41 Minutes.
Hope this helped!
*psst it would help if you gave me brainliest answer, I'm close to ranking up :) Thanks!
Answer:
x = -13
Step-by-step explanation:
6(4x + 50) = 3(x+8) + 3
24x + 300 = 3x + 24 + 3
21x + 300 = 27
21x = -273
x = -13
