Here is an addition sentence. 7 + 4 = 11 choose the related addition sentence that shows the commutative property of addition.. a. 4 + 7 = 11 b. 11 – 4 = 7 c. 11 = 7 + 4 d. 8 + 3 = 11

For this case, we have the expression given by:

This expression turns out to be generic.

The commutative property of the addition states that the order of the addends does not alter the sum. Thus it is concluded that the previous expression above can be written as:

In this way , applying the commutative property of the addition, it can be written as:

Option A

-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

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
