Answer:
3 inches
Step-by-step explanation:
(2 + 2x)(3 + 2x) = 72
4x² + 4x + 6x + 6 - 72 = 0
4x² + 10x - 66 = 0
2x² + 5x - 33 = 0
Using quadratic formula:
x = (-5-17)/4, (-5+17)/4
x = 12/4 = 3
Answer:
4
Step-by-step explanation:
<em>4 is the rate because if she can make 4 in 10 min the the constant would be 4. By the way this didnt get answered becasue it was posted in spanish!</em>

The python is 2.6pi meters long. This is the circumference because it's the distance around the circle. So, C = 2.6pi
We will plug this into the formula below and isolate r
C = 2*pi*r
2.6pi = 2*pi*r
2.6 = 2*r .... divide both sides by pi
2.6/2 = 2r/2
1.3 = r
r = 1.3
Since r = 1.3, this means that the radius is 1.3 meters.

Answer: D
Step-by-step explanation:

Let's take one of the equations and solve for a variable to use the substitution method.

Now replace this in the first equation.

Separate the terms.

Solve 20/5

Subtract 4 from both sides to isolate y.


Solve the difference.



Multiply by the reciprocal or the inverted fraction that is next to y to isolate it.


Now, in order to find x, replace y in any of the two equations.
