Hi there!
Your answer is:
p(1.75) = 5.875
Step-by-step explanation:
p(1.75) means to plug in 1.75 for x
p(1.75)= 2(1.75)^2 + 5(1.75) - 9
6.125 + 8.75 - 9

Answer:</h2>
-18x^5-204x^4-722x^3-600x^2+672x-128
<h2>
Explanation:</h2>


There are multiple ways to solve this for example the foil method or the box method. I prefer to do the box method.
First we are going to set it up
After we set it up we have to solve it so first we are going to multiply

We have to add the exponent




Now we have to add them
-18x^5 stays because there is nothing to add to
Now we add the rest



And -128 stays the same

The answer is
-18x^5-204x^4-722x^3-600x^2+672x-128
<span>The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus:
x^2 - 36 = 5x
x^2 - 5x - 36 = 0
x^2 + 4x - 9x - 36 = 0
x(x + 4) - 9(x + 4) = 0
(x - 9)(x + 4) = 0
x - 9 = 0 or x + 4 = 0
x = 9 or x = -4
Therefore, the positive solution of x^2 - 36 = 5x? is 9.</span>
So 3 parts pineapple juice to 5 parts orange juice
That is a total of 8 parts
the pineapple is 3/8 of the pitcher
the orange juice is 5/8 of the pitcher
