Answer:
(x2+3) • (x2+9)
Step-by-step explanation:
Factoring 
The first term is, 
its coefficient is 1 .
The middle term is, 
its coefficient is 12 .
The last term, "the constant", is +27
Step-1 : Multiply the coefficient of the first term by the constant 1 • 27 = 27
Step-2 : Find two factors of 27 whose sum equals the coefficient of the middle term, which is 12 .
27 + 1 = 28
9 + 3 = 12 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and -3
x4 + 9x2 + 3x2 + 27
Step-4 : Add up the first 2 terms, pulling out like factors :
x2 • (x2+9)
Add up the last 2 terms, pulling out common factors :
3 • (x2+9)
Step-5 : Add up the four terms of step 4 :
(x2+3) • (x2+9)
Answer:
2 7/10
Step-by-step explanation:
3/4+3/5=
Common Denominator: 20
Multiples of 4: 4, 8, 12, 16, 20
Multiples of 5: 5, 10, 15, 20
3x5=15
4x5=20
15/20
3x4=12
5x4=20
12/20
15/20+12/20= 27/20 = 2 7/10

Answer:
Slope = 6
Step-by-step explanation:
Reading your description carefully, the equation of line has been given to be
When we compare this with the standard form of a straight line
We immediately see that the slope or gradient m = 6.
Alternatively, when we consider the coordinates of the points mentioned, we have
(1, 5) ; (0, -1) ; (-1, -7)
We can take any two points out of these three and calculate the slope using the formula
For example, let us consider the points (1, 5) and (-1, -7)
Here x₁ = 1; x₂ = -1 and y₁ = 5; y₂ = -7
Plugging the numbers in the above formula, we have
This agrees with what we calculated directly from the equation of the line!
Hence, slope of the line on the graph = 6
