(36 - 3 x 4) \ (15 - 9 \ 3) = could someone me with this. the answer i got was 66 is this correct? any advice would be appreciated.

Step-by-step explanation:

Multiply the numbers

(36-3 x 4) / (15-9/3)

(36-12) / (15-9/3)

Divide the numbers

(36-12) / (15-3)

Subtract the numbers

(36-12) / (15-3)

24/(15-3)

Subtract the numbers

24/(15-3)

24/12

Divide the numbers

24/12

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

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
