Answer:
The factored form of this would be (x + 4)(x + 9)
Step-by-step explanation:
In order to determine the numbers in the parenthesis, we need to find numbers that multiply to the constant (36) and add up to the middle term (13). In order to do that, we list the factors of the constant and look for those that add up to 13.
1, 36
2, 18
3, 12
4, 9
6, 6
As you can see, 4 and 9 are the only pair that satisfy the stipulations. So we place them in a parenthesis with x's and express as the following.
(x + 4)(x + 9)
Answer:
first one and the biology one
Answer:
e.29 d.1
Step-by-step explanation:
we will replace with the values we have :
- 300 that's a big number . Obviously it isn't a solution
- 50 : 30+50 = 80>60 so no
- 45: 30+45= 75 >60 so no
- 30+30 = 60 we have < not ≤ so no
- 1 yes . it's obvious
- 29 +30 = 59<60 so yes !

In order to find the vertex of a parabola, we use the following formula:

Remember, a parabola looks like so:

Now we know what a and b stand for.
In this case, b is -4, and a is -1:

Simplify:

Divide:
