Answer:
vertex form is y=a(x−h)2+k. To solve this you have to complete the square with the x terms: y= 3x2−12x+4. first isolate the x terms: y−4=3x2−12x. ax2+bx+c to complete the square a=1 and c=(12b)2.

Answer: 12.6 + b = 15.7
Step-by-step explanation:
Here a be the length of equal sides of the isosceles triangle and b be the length of the base of the triangle,
And, the given equation that model the given situation is,
2 a + b = 15.7
Since, a = 6.3,
By putting this value in the above equation,
We get,
2 × 6.3 + b = 15.7
⇒ 12.6 + b = 15.7
Which is the required equation that will use to find the base of the triangle.

Answer:
The answer to your question is below
Step-by-step explanation:
Use proportions to solve these problems
1)
(6x - 6)/35 = (3x + 7)/24
Solve for x
24(6x - 6) = 35(3x + 7)
Expand
144x - 144 = 105x + 245
144x - 105x = 144 + 245
39x = 389
x = 389/39
x = 9.97
2) 9 + x = 6 + 15
Solve for x
x = 21 - 9
x = 12
