Answer:


Step-by-step explanation:
for this equation
a=3
b= -5
c = -7
The sum of equal to

and the product is equal to

. All you do is replace the values. You can prove both of those using the quadratic formula.
ANSWER:
14.5 pounds
STEP-BY-STEP EXPLANATION:
We know the capacity of each bag, therefore, we can calculate the capacity of 2.5 bags, multiplying by the capacity of one, like this:

Which means 2.5 bags contain a total of 14.5 lbs.
Answer:
Step-by-step explanation:
The total length of triangle is 40 in. The length of the right triangle is the total length divided by 2 which 40/2 = 20.
We have 2 right triangles. We can use the pythagorean theorem to solve for x.
a^2 + b^2 = c^2
x^2 + 20^2 = 25^2
x^2 + 400 = 625
- 400 - 400
x^2 = 225
x = 15
Its A God bless. Hopefully, this is right
