Answer:


Step-by-step explanation:
<u>Quadratic Equation Solving</u>
We have the equation:

Divide by 8:

Now complete the squares so the left side is a perfect square of a binomial:

Factoring the perfect square:

Taking the square root:

The square root of a negative number is an imaginary number:

Solving for x:

The solutions are:


So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

Now that we've factored our equation, we can use ZPP and break it up:

So, our solutions are:

Answer:
Slope(m) = 16
Y intercept (c) = 23
Step-by-step explanation:
Given:
Points : (x1, y1) = (2, 55)
(x2, y2) = (4, 87)
Using two point form to calculate slope:


m = 16
To find y intercept:
Take any one point ans slope :
Using slope point formula:
y = mx + c
87 = 16(4) + c
Solving for c:
c = 23
Answer:
She can fill 9 containers
Step-by-step explanation:
you do 6 3/4 dived by 3/4 and you get 9
By pulling out the common factors for each pair of terms, we can rewrite the original polynomial like this:
3x(2x + 1) + 10(2x + 1)
These two terms now have a common factor of (2x + 1). Seems like we should be able to do something with that information, don't you think? In fact, we can pull out this common factor and rewrite the polynomial again:
