Step-by-step explanation:
4x²-9
4x²+6x-6x-9
4x²+6x-6x-9
2x(2x+3)-3(2x+3)
2x(2x+3)-3(2x+3)
(2-3)(2x+3)
solution
(8x-3)(2x+3)
Step-by-step explanation:
a =2πr^2
=2π8m^2
=2π64m^2
=128πm^2
Answer:
D
Step-by-step explanation:
This question is written very poorly because it is hard to know what x represents, as well as the end equation. I have come to the conclusion that x represents the amount of days and the end equation represents the exact same equation given (as it asks to rewrite the equation)
So, it is obvious that only one equation matches the one given -- as (1.03)^7 is approximately 1.23, which is close enough to 1.25 (compared to the other options), D is our answer
A and B have both 1.25^7 = around 4.77 (480% ish), and C has 1.03^x, which is not very close to 1.25
I think so 12 to 13 minutes will it take to use all sheets..
Answer:
D. X=7
Step-by-step explanation:
Use the order of operations to solve this problem.
First, combine like terms.
7x-5x=2x
Our equation is now 2x-3=x+4
Now, add 3 to both sides.
Our equation is now 2x=x+7
Subtract x from both sides.
x=7
The answer is D. X=7
