Answer:
11.x=16 12.x=37
Step-by-step explanation:
11.
20^2-12^2=x^2
256=x^2
x=√256
x=16
12.
13^2-5^2=y^2
144=y^2
y=12
/
y^2+35^2=x^2
12^2+35^2=x^2
1369=x^2
x=37

Answer:6
Step-by-step explanation:
We have three groups of cookies as follows:
24 oatmeal
36 vanilla bean
42 chocolate chip
If we breack down into factors we get
24 2 24 = 2³ * 3 36 2 36 = 2²*3³ 42 2 42 = 2*3*7
12 2 18 2 21 3
6 2 9 3 7 7
3 3 3 3 1
1 1
Fom where we can get that biggest common factor is 6
24 ÷ 6 = 4
36 ÷ 6 = 6
42 ÷ 6 = 7
Then Bakery will have 4 groups of oatmeal cookies, 6 of vanilla bean, and 7 chocolate chip
