First, we'll want to write out the equation

then reduce what we can

so this means n can equal any whole number between 9 4/9 & 12, which gives us the options of {10,11}
Step-by-step explanation:
(2c+c) + 12 =78
3c + 12 = 78
78 - 12 = 66
66 ÷ 3 = 22
22 + 22 + 22 + 12 = 78
{ C = 22 }
Answer:
D) AD=21
Step-by-step explanation:
QD=1/2 AQ
QD=1/2(14)
QD=7
AQ+QD=AD
AD=14+7
AD=21
ANSWER
The graph has no zero.
EXPLANATION
The given polynomial function is a quadratic graph that has its maximum point at

The graph has no x-intercept.
This implies that, the polynomial function represented by this graph has no zeros.
