Answer: 100 square feet
How many square feet is a 10x10 room? The square footage of a room 10 feet wide by 10 feet long is 100 square feet. Find the square footage by multiplying the width (10 ft) by the length (10 ft).
-w is the variable, so our goal is to get it on the left side of the equal sign and keep the 15 on the right side.
distribute the -2 to each term inside the parentheses. the equation should now look like this:
2w - 6 = 15
now, we must transpose the -6 to the other side of the equation. remember, we're moving it across the equal sign, so it becomes a positive 6.
2w = 21
now divide each side of the equation by 2 so the variable is alone.
w = 10.5

Answer:
No, not really.
dividing 25 into 4 equal groups, equals 6.25.
So no, you can not divide 25 into 4 equal group.
If if was 25 into 5 equal groups, then yes.
Hope this helps!!!

Step-by-step explanation:
Your answer would be 135.
This is because angles on a straight line add up to 180°, and so we need to subtract 45 from 180, which gives us 135.
