Answer:
A is the correct option.
Step-by-step explanation:
We need to evaluate the expression 3 plus 5, multiplied by, the quantity h minus k, divided by 4, when h = 4 and k = 12. It can be written as :
![(3+5)\times \dfrac{h-k}{4}](https://tex.z-dn.net/?f=%283%2B5%29%5Ctimes%20%5Cdfrac%7Bh-k%7D%7B4%7D)
Put h = 4 and k = 12 in above expression.
So,
![(3+5)\times \dfrac{h-k}{4}=(3+5)\times \dfrac{4-12}{4}\\\\=8\times \dfrac{-8}{4}\\\\=2\times -8\\\\=-16](https://tex.z-dn.net/?f=%283%2B5%29%5Ctimes%20%5Cdfrac%7Bh-k%7D%7B4%7D%3D%283%2B5%29%5Ctimes%20%5Cdfrac%7B4-12%7D%7B4%7D%5C%5C%5C%5C%3D8%5Ctimes%20%5Cdfrac%7B-8%7D%7B4%7D%5C%5C%5C%5C%3D2%5Ctimes%20-8%5C%5C%5C%5C%3D-16)
After solving we get that the value of the given expression is -16.

Answer: ![810m^{2}](https://tex.z-dn.net/?f=810m%5E%7B2%7D)
Step-by-step explanation:
First, we divide the composite figure into two distinct geometric shapes. This would be a triangle and a square. To find the triangle we use the formula:
A = 1/2bh
To find the base of the triangle we can add:
9 + 9 + 18 = 36
Now we plug in and solve:
A = 1/2bh
A = 1/2(36)(27)
= 1/2(972)
= 486
To find the square, we can use length x width:
18×18 = 324
Now, we add the sums together:
486 + 324 = 810
