How do I do this as I need help but don’t know how to solve it ??

14 tickets weren't sold.

Step-by-step explanation:

14 times 15 = 210

So there are 210 seats in the cinema.

The total is $1274 so you would divide

which equals 196

Your final step is to subtract

210 (the total seats) minis 196 (seats sold) equals 14 seats not sold

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
