Answer:
9 sqrt 3 in^2
Step-by-step explanation:
Assuming this is a equilateral triangle
find height
sin 60 = height/6
6 sqrt (3)/2 = height
3 sqrt 3 = height
area = 1/2 base * height
= 1/2 * 6 * 3 sqrt 3
= 9 sqrt 3 in^2

Answer:
21a + 17b
Step-by-step explanation:
To simplify, we need to distribute the 9 to the terms inside of the parentheses that it is being multiplied by and 4 to the terms inside of the parentheses that it is being multiplied by like so:
9(a)+9(b)+4(3a)+4(2b)
9a+9b+12a+8b
Add like terms
21a + 17b
