Answer: 4z + 28
Step-by-step explanation:
We can distribute the 4 to each term inside the parenthesis.
So 4(z+7) = 4*z + 4*7
= 4z + 28
The answer would be C.
Sin2 cot2=sin2*cos2/sin2=cos2
Which is not equal to the others.

Answer:
1. $85
2. $90.10
3.$108.12
4.$54.06
Step-by-step explanation:
100-15=85 (15% of 100 is 15)
6 percent of 85 is 5.10. So 85 + 5.10=90.10
20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12
Now divide by 2 to get how much they each will pay 108.12/2 = 54.06
