It has a minimum value at x = 3 and f(x) = 4
Vertex form is
f(x) = a(x - 3)^2 + 4 where a is some constant to be found
From the graph when x = 5 f(x) = 15, so
15 = a * 2^2 + 4
a = 15-4/4 = 11/4
so our equation is f(x) = 11/4(x - 3)^2 + 4
Let's say we had to multiply the two binomials (x + 1)(x + 2). We could use the grid method or FOIL, but we will use the grid method for now. Here is how you do it:
1. Identify all the terms in the expression:
x, 1, x, 2
2. Align the terms in a grid-like fashion according to their binomials:
x 1
x
2
3. Now, multiply all the terms together (ex. x × x is x²)
x 1
x x² 1x
2 2x 2
4. Put all products in decreasing order:
x²+1x+2x+2
5. Combine Like Terms (CLT):
x² + 3x + 2
Therefore, the answer is x² + 3x + 2. As you can see, the grid method is figuratively long, and the FOIL method is definitely recommended. Hope this helped!
14 muffins is 2/5 of your muffins.
In total you had 5/5 muffins, which is 5/2 times more.
Hence you had 14*5/2=35 muffins !
Hence you have 35-14=21 left !

60 --- x%
x = 60/400 * 100 = 15% <span>chocolate.</span>
Answer:
the info I read for the6th time indicates that its possible that angle 3 could be congruent to angle 5 or that angle 2 could congruent to angle 6 I'm honestly not sure just helping to brainstorm
