Factored form: (x + 1/5)(x + 1/4)
Foil: x^2 + 1/4x + 1/5x + 1/20
Simplify: x^2 + 9/20x + 1/20
Hope this helps!
Answer:
I think standard form would be best because it is simplest.

Step-by-step explanation:
With the given points, we can first find the gradient of the line:
gradient = (2+1)/(-4-8)
= -1/4
We also know that the formula of a straight line is
Y = mX+C, where m is gradient and C is y intercept.
Hence by substituting the coordinates (-4, 2) and the gradient -1/4, we get:
2 = (-1/4)(-4) + C
<u>C = 1</u><u>.</u> Hence, Answer is C.
(Actually, you can just draw a straight line connecting the 2 coordinates and find out the y intercept)
Divide total ice cream by serving size:
2/5 / 4/5
When you divide fractions, change division to multiplication and flip the second fraction over:
2/5 x 5/4
Now multiply ht top numbers and the bottom numbers:
(2 x 5) / (5 x 4) = 10/20 = 1/2
There is 1/2 serving.
