Fill in the missing number to complete the linear equation that gives the rule for this table.

y=x-2

Step-by-step explanation:

1) lets substitute a value of y and a value of x to find out what unknown value "b" is

(1)=(3)-b

subtract 3 from both sides:

-2=-b

divide both sides by -1

2=b

so

function rule:

y=x-2

lets check with different points:

2=x-2

4=x

Its right! so this is the rule!

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
