Answer:
15y - 25 = 5 (3y + -5) which makes the equation 15y - 25 = 5 (3y - 5)
Step-by-step explanation:
In order to factor with a GCF, what I like to do is divide the whole first equation by whatever the distributed number in the second equation is.
This makes 3y + -5, which is just 3y - 5.
This makes your answer known. Once you have your answer, insert it BACK into the equation to make sure it is equal. (In this case, I have checked, and it is indeed the correct answer.)
So your answer has been found at this point.
Hope this helps.

Step-by-step explanation:
Answer: 8,100 cm^2
Step-by-step explanation: Area = S^2 so each side is sqrt(900) = 30cm
A square 3 times bigger has sides 30cm*3 = 90cm. The area for that square is 90^2 = 8,100 cm^2
Answer:
30°
Step-by-step explanation:
TW UV
If an ARC subtends an angle in the circle (on the opposite side of the circumference), the measure of that angle will be HALF of the Arc. In other words, the Arc's measure will be DOUBLE of that angle.
The measure of the angle would be SAME if the angle subtended in the center of the circle, thought.
Now, looking at the image, we can see that:
Arc TW subtends Angle V and Angle U
*on the opposite side of the circumference*
So,
Angle V (measure given to be 30) is HALF of Arc TW, so
Arc TW = 2 * 30 = 60
So, Angle U is half of Arc TW
60/2 = 30
Hence,
<u>∠U = 30°</u>
