Answer:
Only the firsts and fourth choices (
and 
)
Step-by-step explanation:
Turn the equation into words:
"A number plus 9"
"Multiplied by 
"
"Is equals to -18"
Distribute to find the second equation:
Step-by-step explanation:
1.) Firstly, you need to count out how many things there are. 4 app, 5 entrees, 2 desserts. This makes 11 different things
2.) for 11 numbers there can be 9 ways for each number for 1st nine places since 0 can't be the fist figure and next two are reciprocated from 10 numbers. Therefore 10!/2!
3.)So 99 combinations have 10!/2! Permutations hence total ways are 99*10!/2!
There would be 432 trading cards. I know because to find the total number of cards you have to multiply 12*36 because on one pack there are 12 trading cards and you have 36 packs.12*36=432
There are 72 stickers because to find the total number of stickers you multiply 2*36 or 36*2 which equals 72
Trading cards =432
Stickers =72

Answer:
B
Step-by-step explanation:
Let y - x = height of sign
tan 31 = x/24
tan 31 • 24 = x
14.4206548567 = x
tan 42 = y/24
tan 42 • 24 = y
21.6096970631 = y
Now subtract x from y.
y - x = 21.6096970631 14.4206548567
y - x = 7.1890422064
Rounding off to the nearest tenth of a foot, we get 7.2 feet.
The sign for the roof is 7.2 feet.
