Answer:
(3x + 4y - 3z)(3x + 4y + 3z)
Step-by-step explanation:
(3x + 4y)² - (3z)² ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Here a = 3x + 4y and b = 3z, then
(3x + 4y)² - (3z)²
= (3x + 4y - 3z)(3x + 4y + 3z) ← in factored form

what is the answer of this question?
9514 1404 393
Answer:
970
Step-by-step explanation:
It turns out that the radical terms cancel, so the result is an integer. You can find the integer value using your calculator. It is ...
(5 +2√6)³ +1/(5 +2√6)³ = 970
_____
The cube of 'a' is ...
(5+2√6)³ = 5³ +3·5²·2√6 +3·5·(2√6)² +(2√6)³
= 125 +3·50√6 +3·120 +48√6
a³ = 485 +198√6
The reciprocal of this is ...
b³ = 1/a³ = 1/(485 +198√6) = (485 -198√6)/(485² -6·198²) = (485 -198√6)/1
b³ = 485 -198√6
Then the sum is ...
a³ +b³ = (485 +198√6) +(485 -198√6) = 970
Simplify. 28x^2/7x^6
Answer:
4x^8

Write the equation for the line passing through points (0, 0),(4, 5), and (8, 10).
Answer:
y=5/4x
Step-by-step explanation:
The equation for the line passing through points (0, 0),(4, 5), and (8, 10) is; y = (5/4)x
From the coordinate, (0, 0), we can conclude that the y-intercept of the line is 0.
In essence, to determine the equation of the line, we must evaluate the slope by consider two points on the line namely;
(4, 5), and (8, 10).Slope, m = (y2 -y1)/(x2 - x1).
Slope, m =( 10 - 5)/(8-4)
m = 5/4.Therefore, the equation of the line is;
y = (5/4)x.Read more on equation of a line;
