Find the number that must be added to each expression to form a perfect square trinomial. then write the trinomial as a binomial squared.

x^2+7x+

( )^2

i.

ii.

Step-by-step explanation:

The give expression is

We need to find half the coefficient of and the square the result.

Half of is .

When we square it, we get;

Hence we add to obtain;

The expression as a binomial squared is

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.
