Answer:
(3a+4)(9a^2-12a+16)
Step-by-step explanation:
It's a perfect square :)
The factors of the given polynomial are (4+3a)(9a²-12a+16)
What is polynomial?A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using mathematical operations.
Given that, a polynomial, 64+27a³
Using identity : a³+b³ = (a+b)(a²-ab+b²)
We get,
= (4+3b)(4²-4x3a+(3a)²)
= (4+3a)(16-12a+9a²)
Hence, the factors of the given polynomial are (4+3a)(9a²-12a+16)

find F(-6)
Answer:
The answer is -107
Step-by-step explanation:
A charity organization had to sell a few tickets to their fundraiser just to cover necessary production costs after selling 10 tickets, they were still a net loss of $800 (due to the product cost). They sold each ticket for $70 let y represent the net profit (in dollars) when they have sold x tickets
Answer:
y = 70x - 1500
Step-by-step explanation:
Price per ticket = 70
Using the relation :
y = mx + c
x = number of tickets sold
When x = 10 ; y = - 800
Hence,
-800 = 70(10) + c
-800 = 700 + c
-800 - 700 = c
Hence, c = - 1500
The equation for the net profit in dollars is :
y = 70x - 1500

Find the value of x that makes m || n
(2x+20) 3x
Answer:
x = 20
Step-by-step explanation:
For the lines to be parallel, then (3x + 20) and (3x) are alternate angles and congruent, thus
3x = 2x + 20 ( subtract 2x from both sides )
x = 20

A thermometer manufacturer compares the reading on one of its thermometers to a thermometer that they know is accurate. The accurate thermometer reads 25 degrees Celsius. Their thermometer reads 30 degrees Celsius. What is the percent error in their thermometer's reading?
A.2%
B.20%
C.83%
D.16%
Answer:
B. 20%
Step-by-step explanation:
Percentage Error = (Actual Value - Expected Value) / Expected Value * 100
Actual Value = 30
Expected Value = 25
Percentage Error = (30 - 25) / 25 * 100
Percentage Error = (5) / 25 * 100
Percentage Error = 0.2 * 100
Percentage Error = 20
