Answer:
Step-by-step explanation:
7) 2ab + 4ac = 2*a*b + 2 *2 *a*c
= 2a(b + 2c)

8) ac - a²c² = c( a - a²c)
bc - abc = c(b - ab)


9) b²+ 4b - 5 = b² + 5b - 1b - 5
= b(b + 5) - 1(b + 5)
= (b +5)(b - 1)
b² + 8b + 15 = b² + 5b + 3b + 15
= b(b + 5) + 3(b + 5)
= (b + 5 )(b + 3)


The total amount of interest earned each year will be
5.2% × $1,500,000 = $78,000
_____
We would need to know more about the beneficiaries (their number and the way they might split the proceeds) and how they might use the balance in the account (whether interest only, or interest and principal are withdrawn) before we could answer the question asked.
Answer:
17c - 2
Step-by-step explanation:
Firstly, add the normal numbers together:
7c + 4 + 10c - 6
4 - 6 = -2
7c + 10c - 2
Now, the two numbers with a c value can be added together:
7c + 10c = 17c
This returns the answer:
17c - 2

Step-by-step explanation:
Diameter of cone = d = 4mm
So,
Radius of cone = r = 2mm
Slant Height = l = 6mm
Surface Area = A = ?
The formula for the surface area of cone is:

Using the values, we get:

mm²
Therefore, the surface area of the cone with diameter 4mm and slant height of 6mm will be 16π mm²
