Remark
What this is trying to tell you is that you have two factors. Each in turn can be zero, but they cannot be zero at the same time. You will get that kind of question, just not now.
So either - n = 0 or 5n - 4 =0
Solution
- n = 0 Multiply both sides by - 1
(-1)*(-n) = 0*-1
n = 0
5n - 4 = 0 Add 4 to both sides.
5n = 4 Divide by 5
n = 4/5
Comment
B and D are both wrong 4/5 is positive. and those list n as -4/5 which is wrong.
A is wrong because the function will not go to 0 if n = -1
Answer
C <<<<Answer
Answer:
$4.90
Step-by-step explanation:
If 5 cakes equal 3.50. We must divide 3.50 by 5 to see the price of just one cake. Now since 3.50/5 is 0.70. We must multiply 0.70 by 7. Since we have 7 cakes. Now we get our simple answer of $4.90.

Answer:
64 + 64sqrt(3)
174.9 cm²
Step-by-step explanation:
AD/2 = 8cos(60) = 4
AD = 8 cm
Height of each triangle = 8sin(60)
= 4sqrt(3)
sqrt: square root
Area = 8² + 4(½ × 8 × 4sqrt(3))
= 64 + 64sqrt(3) cm²
= 174.8512517 cm²
Simplify:
8/36=4/18=2/9=0.22222(repeating)
Your answer would be 2/9 or 0.22222(etc.).
I hope this helps :)
