Answer:
x=52
y=25
z=90
Step-by-step explanation:
x= 180-38-90=52
y= 180-(65+52)-38=25
z=180-65-25=90
The answer is: [B]: " -10a + 6b² − 4b + 3 " .

Explanation:
____________________
Given:
____________________________
-2(5a − 3b²) − 4b + 3 ;
_________________________________
"Use the distributive property [of multiplication] to expand the expression."
______________________________________________
Note the distributive property of multiplication:
______________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
______________________________________________
So, we have: " -2(5a − 3b²) − 4b + 3 " ;
______________________________________________
Start with: " -2(5a − 3b²) " ;
______________________________________________
-2(5a − 3b²) = (-2*5a) − (-2*3b²) = (-10a) − (-6b²)
= -10a + 6b²
________________________________________________
→ Now, bring down the rest of the problem;
________________________________________________
-10a + 6b² − 4b + 3 ; which is: Answer choice: [B].

Answer:
See explanation below.
Step-by-step explanation:
a) c(0) = 10
Here, t = 0 and c(0) = 10
At 8 A.M., there are 10 customers.
b) c(6) = c(7)
6 hours after 8 am is 2pm
7 hours after 8 am is 3pm
They are equal. So it means
There are the same number of customers at 2pm and at 3pm
c)
c(k) = 0
There are no customers, k hours after 8 am
d)
c(4) > c(3)
4 hours after 8 am is 12pm
3 hours after 8 am is 11am
This means:
The number of customers at 12pm is greater than the number of customers at 11am
