Answer:
perimeter is 12x-6
Step-by-step explanation:
perimeter is the sum of all sides
3(x+2) + 2x+11 + 7x-23
distribute the 3 in the first term, then combine 'like terms'
3x+6 + 2x+11 + 7x-23
3x+2x+7x + 6+11+(-23)
12x-6
The answer in standard form is 86,400
Answer:
The vertex will be found at (-5, -28)
Step-by-step explanation:
Vertex form uses the following formula:
y = a(x-h)^2 + k
Identify the values of h and k in your function:
(x+5)^2 - 28
h = -5, k = -28
The vertex is found with the following point:
(h,k)
Vertex: (-5, -28)
The vertex will be found at (-5, -28)
