Answer:
answer down below
Step-by-step explanation:
it would be 315
Y= x²- 6x +7
Vertex form is y= a(x-h)² +k
The vertex form of this equation would be y= (x-3)²- 2 because if we transform to the standard form it would be equal to y= x²-6x+7 so we just have to complete the perfect square (which means to complete, following the rules, with the numbers that will make this equation right in the standard form).
How our x² is equal to 1 on our standard form (like it is not 2x², it is just x²), our ''a'' on the vertex form is 1 so we simply don't have to write the 1 in front of it so it stays y= 1(x-3)² -2 or y=(x-3)²-2. Look how it works: (x-3)² we use the rule of a²+2ab+c² which is the square of the first x² plus two times the first term times the second -6x plus the square of the last term (-3)² = 9 so we have x²-6x+9 - 2 that gives us the standard form x²-6x+7. So, that's true that the vertex form is y=(x-3)²-2
Answer:
9x^2 +12
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
= 3 *(3x^2 +4)
Distribute
= 9x^2 +12
Answer:
DE
Step-by-step explanation:
You can tell by the markings. Since there are two vertical markings it concludes that those sides are the same length.
