Answer:
I'm guessing the answer is B againn XD
must be a lucky day for B!!
Explanation:
Kadisha's method works because 15% is 3 times 5%, and both amounts are computed on the amount of the bill before tax is added.
F(x)= 2x²+4x-6 and g(x)=2x-2, find each function
1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)
First factor both top and bottom:
(2x-2)(x+3)÷(2x-2) = x+3
2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->
2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:
2a^2+8a+8+4a+2, combine like terms
2a^2+12a+10
3. g(a/2) = plug (a/2) in anywhere there's an x in g(x)=2x-2:
2(a/2)-2 = a-2
615.44 = (3.14)(radius)^2
<span>radius = square-root of (615.44/3.14) </span>
<span>diameter = radius x 2 </span>
<span>diameter = 28 inches
3.14

Let T be total number of milligrams of vitamin C in our salad.
We have been given that there are s milligrams of vitamin C per milliliter of spinach, B mg per milliliter of berries, and D mg per milliliter of dressing.
Let us find how much mg of vitamin C our each ingredient of salad will have.
We have been given that a salad contains 300 milliliters of spinach, 200 ml of berries, and 42 ml of dressing.



To find total milligrams of vitamin C in our salad we will add milligrams of vitamin C in each of three ingredients of salad.
Therefore, our desired expression will be
