List the four types of organic macromolecules. Provide specific molecular examples of each.
The least common factor of x and x squared is x
Answer:
26.88 mm
Step-by-step explanation:
4.2 x 12.8 = 53.76/2 = 26.88
We can factor this by using grouping. Take the leading coefficient and multiply it by the constant. In this case we get 5*-7 = -35.
Now we need 2 numbers that add to 2 and multiply to be -35. The numbers are -5 and 7.
So split the 2r into these two terms and group.
(5r^2 - 5r) + (7r - 7)
Factor both groups.
5r(r-1) + 7(r-1)
The factors of (r-1) can be added together to get the answer.
(r-1)(5r+7)
