Will give brainlest answer to who answers eva is showing her work in simplifying (7.3 – 7.2) – 3.8 + 3.7. in which step did eva make an error? step 1: (7.3 – 7.2) – 3.8 + 3.7 step 2: 7.3 + (–7.2 – 3.8) + 3.7 (commutative property) step 3: 7.3 – 11 + 3.7 step 4: 7.3 + 3.7 – 11 (commutative property) step 5: 11 – 11 = 0 step 2; she wrote commutative instead of distributive step 4; she wrote commutative instead of distributive step 4; she wrote commutative instead of associative step 2; she wrote commutative instead of associative

-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

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
