Answer:

C. (x-2)^2=7

Step-by-step explanation:

What you have to do first is to get rid of the 3 in the x^2 so you will divide 3 by the whole thing to get x^2-4x=3.

You will then divide -4 by 2 and then square the answer to get 4.

You will then add the 4 into the end of the equation and to the 3 to get x^2-4x+4=7.

You will then make into a perfect square (x-2)^2=7 and that is your answer.

mylen [45]

Answer:

3.8m

Step-by-step explanation:

Since Lara is putting lace trim around the border of a circular tablecloth, by the time she finishes she has covered the circumference.

The circumference of a circle is calculated using:

$C=\pi \: d$

where d is the diameter of the circle.

It was given that the diameter of the circular table cloth is 1.2 meters.

$C=3.14 \times 1.2$

$C=3.768$

Therefore the length of the lace she needed is 3.8m

4x+2(3x-9)=42
first we want to distribute the 2 using the distributive property
4x+6x-18=42
Then we simplify
10x-18=42
we add 18 to both sides
10x=60
divide both side by 10
x=6
