Please answer asap if u know the answer!!!! completing a square. thank you!!!!
Tema [17]

Answer:

D

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form using the method of completing the square.

Given

f(x) = 3x² - 24x + 10

We require the coefficient of the x² term to be 1 , thus factor out 3

3(x² - 8x) + 10

To complete the square

add/subtract ( half the coefficient of the x- term )² to x² - 8x

= 3(x² + 2(- 4)x + 16 - 16) + 10

= 3(x - 4)² + (3 × - 16) + 10

= 3(x - 4)² - 48 + 10

= 3(x - 4)² - 38, thus

f(x) = 3(x - 4)² - 38 ← in vertex form

If the answer is D. the equation to represent the ages of students is:
n + n+1 + n+2 = 45
it is showing that  n is the age of one student and the other student has age one year more than the first one and third students has age of 2 years more than first student and one year greater than the second student. if we solve this equation for the value of n, we get;
3n + 3 = 45
3n = 45 -3
3n = 42
n = 14
so the age of one student is 14, second student 15 and third student 16 years.
and if we add there ages, 14 + 15 + 16 = 45

Carla bought a piece of ribbon that measured 1 meter in length. She used 1/4 of the ribbon on a gift box. She used 1/8 of the ri
lord [1]

1/4 is equal to 2/8.

2/8+1/8=3/8

Carla used 3/8 of the ribbon in all. So, 5/8 of the ribbon is left.

I hope this helps :)
