Using the completing-the-square method, rewrite f(x) = x2 - 6x + 2 in vertex form.

sp2606 [1]

Answer:

$\large\boxed{f(x)+(x-3)^2-7}$

Step-by-step explanation:

$\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\\\\f(x)=x^2-6x+2=x^2-2(x)(3)+1=x^2-2(x)(3)+3^2-3^2+2\\\\\text{Use}\ (a-b)^2=a^2-2ab+b^2\to x^2-2(x)(3)+3^2=(x-3)^2\\\\f(x)=(x-3)^2-9+2=(x-3)^2-7$

Mrs. Duncan measured the lengths of a crayon and a pencil. The pencil is double the length of the crayon. The sum of their lengt

Margarita [4]

Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

Step-by-step explanation:

Let the length of crayon = $x$

Length of a pencil = $2x$

As according to question that the sum of their length is 24 centimetres

So we have

$x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8$

Therefore the length of crayon = 8 centimetres

Length of pencil= $2x= 2\times x = 2\times 8 =16$ centimetres

Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
