Take out the GCF
5(2x^2+3x-14)
Use slip and slide for the inner trinomial
x^2+3x-28
(x+7)(x-4)
(x+7/2)(x-4/2)
(2x+7)(x-2)
Final answer: 5(2x+7)(x-2)

Answer: 4865</h3>
=======================================================
Explanation:
The sequence {3,11,19,...} is arithmetic since we are adding 8 to each term to get the next one
etc. This means the common difference is d = 8.
The first term is a = 3
Let's use this formula
S = n*(2*a + d(n - 1) )/2
so we can find the sum of the first n terms. In this case, n = 35
So,
S = n*(2*a + d(n - 1) )/2
S = 35*(2*3 + 8(35 - 1) )/2
S = 35*(6 + 8(34))/2
S = 35*(6 + 272)/2
S = 35*(278)/2
S = 35*139
S = 4865
Answer:
On average she looses 1.33 pounds per week
Step-by-step explanation:
3/4=0.75
1.25+2+0.75=4 -> total weight loss
There are 3 weeks in total.
4/3=1.33
