#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
Answer:

Step-by-step explanation:
Answer:

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

where,

So, the area of the quadrilateral is

12. 4(s+5)
4s+20
15. 2(3r-12)
6r-24
18. -3(16-3d)
9d-48
Answer:
40
Step-by-step explanation:
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.
