How do i go about solving the problem?

See below.

Step-by-step explanation:

You have already drawn the line x = -1 . This is the vertical line passing through the point F.

So if we reflect across this line, F will stay where it is at (-1,-1)  (because F is on the 'mirror'). E is 3 units in front of the line so is reflected 3 units the other side.

The image of E, E' will be at (2, -3). The image of G, G' will be at (-2,-3).

The image of G, G' will be at (-2,-3).

Step-by-step explanation:

if you look closely it is basic math!

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
