Find the area of the following
kite:
10 cm
4 cm
4 cm
4 cm

56cm²

Step-by-step explanation:

First I started to multiply the 4 by 4 triangle. 4x4=16. Since there are to triangles with the same lengths there wouldn't be any point of dividing the 16 because I would just add it right back. So now you have the area of two triangles which is 16. For the two isosceles triangles I would multiply 10 by 4 and do the same thing by not dividing it by 2 because it wouldn't make a difference when I added the other triangle. So now you have two areas 16 and 40 all you have to do is add them together and you have your answer.

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
