X² - 21x + 110
first you break it up into two parenthesis & since x is squared you need two x's
since 110 is positive and 21 is negitive, both of your signs need to be negitive
(x - ?)(x - ?)
then you need to think! what are the factors of 110?
Which of these factors add up to 21? those factors go in the parenthesis
Does this Help? Let me know if you need anything!
Then answer should be w = 4/3 if that’s what you lookin for
Area of a semicircle =

r² / 2
r= 5/2 = 2.5
So: A= 3.14 x 2.5² / 2 A = 9.8125 so rounding to the nearest hundredth is A=9.81
As already mentioned, the volume for a rectangular prism, namely a box in this case, is just the product of its dimensions, length * width * height.

now, as far as another one... hmm is easier if you post in the channel, that way I can include any graphs if needed or tables and such.
so, what happens if you double up the dimensions?

notice, how many times the new size is, is 8 times the original.
