Answer:
39
Step-by-step explanation:
square= lw
triangle= 1/2lw
s=9
triangle=15 divided by 2 times 4=30
you add 30 + 9 which will give you 39
12 - 3 = 9
3 + 9 = 12
12 - 9 = 3
3a + 3b, for a=2 and b=4 ... The first thing you'd do would be to plug the numbers in -
3 x 2 + 3 x 4
Then multiply them -
6 + 12
Then add -
18.
So your answer should be 18.
