I hope I helped! Also, one thing when you adding decimals or multiplying them, pretend the decimal point isn't even there. Then, once you have your answer, you just add the decimal in the middle. Basically just adding like in first grade! Super easy and I hope I helped!
To complete the square you take the coefficient of the 'b' term (10), divide it by 2 (10/2), then square it (5^2 = 25). This is the number you add.
Letter C 25
Answer:
Take 25 percent of the number and subtract that
Step-by-step explanation:
Basically, to decrease by 25 percent, you either multiply the number by .75 to get 75 percent of the original 100 percent. You do this because decreasing 100 percent (the original number) by 25 percent will give you 75 percent of the original number. If that's too confusing, take 1/4 of the original number and subtract that from the original number.
