Answer:
Its A
Step-by-step explanation:
You are going to bake cookies. You need 1 1/8 cups of material. You have 3/4 cups of flour and 1/8 cups of milk. How much sugar do you need if you already have 7/8 cups worth of material?
(Hint:1 1/8 (one and one-eighth) = 9/8)
9/8( The amount of material we need) - 7/8(the amount of material we have)
= 2/8 or 1/4
You will need 1/4 cup of sugar.
Given equation: y =2x^2+12x+13.
We need to find the axis of symmetry and the coordinates of the vertex of the graph of the function.
The formula of axis of symmetry is : .
a= 2 and b=12.
Therefore, .
<h3>Therefore, axis of symmetry is x=-3.</h3>
Let us find y-coordinate of the vertex.
Plugging x=-3 in given quadratic y =2x^2+12x+13.
y= 2(-3)^2+12(-3)+13 = 2(9) -36 +13 = 18-36 +13 = -5.
We got x-coordinate of the vertex -3 and y-coordinate of the vertex -5.
<h3>Therefore, vertex of the graph is (-3,-5).</h3>
Distributive property: <em>a(b + c) = ab + ac</em>.
We have 18 + 24
18 = 6 · 3
24 = 6 · 4
Therefore
18 + 24 = 6 · 3 + 6 · 4 = 6 · (3 + 4)
<h3>Answer: 18 + 24 = 6 · (3 + 4)</h3>
