In a two-digit number, the tens digit and the double that of the units. Reversing the figures of this
number and multiplying the number with the digits reversed
for 2, the result is a number that exceeds
12 the number you are looking for. What is the number?

I know the answer (84), but I need to say how I got it lol

will give brainliest​

step-by-step explanation:

1) is right

step-by-step explanation:

-3

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

i would say b) is your answer

sorry if im wrong
