#1: 4(x + 3)

We just have to distribute the 4 throughout the rest of the problem. So, (4 times x) + (4 times 3) = 4x + 12

#2: -7(4 - y)

This is the same concept, but with a negative sign at the front. So, (-7 times 4) - (-7 times y) = -28 + 7y

Kite A B C D is shown. Lines are drawn from point A to point C and from point B to point D and intersect. In the kite, AC = 10 a
Oduvanchick [21]

Answer:

30 u^{2}

Step-by-step explanation:

The computation of the area of kite ABCD is shown below:

Given data

AC = 10 ;

BD = 6

As we can see from the attached figure that the Kite is a quadrilateral as it involves two adjacent sides i.e to be equal

Now the area of quadrilateral when the diagonals are given

So, it is

\text { area of kite }=\frac{1}{2} \times d_{1} d_{2}

where,

d_{1}=10\ and\ d_{2}=6

So, the area of the quadrilateral is

=\frac{1}{2}(10)(6)\\\\=30 u^{2}

180 degrees for a triangle. We add 87 and 53 degrees.

That equals 140. Again, back to 180 degrees. We minus 180 degrees with 140 degrees which equals:

40 degrees.
