Constant in a mathematical expression is a term whose value never changes.
The terms with x and y will vary based on the variable x and or y.
No, it is not.
4/7 ≈ 0.5714
3/5 = 0.6
Actually, 3/5 is greater than 4/7.
Another way you could do this is by multiplying 4/7 with 5/5 and by multiplying 3/5 with 7/7.
4/7 * 5/5 = 20/35
3/5 * 7/7 = 21/35
Have an awesome day! :)
I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES.
PLEASE SEE ATTACHED IMAGE.
For this case the area is given by:
A = (22 + x) * (28 + x) = 722
Rewriting we have:
616 + 22x + 28x + x ^ 2 = 722
x ^ 2 + 50x + 616 - 722 = 0
x ^ 2 + 50x - 106 = 0
Solving the polynomial we have:
x1 = 2.04
x2 = -52.04
We take the positive root:
x = 2.04 inches:
Answer:
The width of the border to the nearest inch is:
x = 2inches
Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
We have given velocity as function of t 
Acceleration is equation rate if change of velocity with respect to time
So 
(a) Acceleration at t = 5 sec
(b) Acceleration at t = 10 sec
(c) Acceleration at t = 20 sec
