Answer:
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)
Step-by-step explanation:
(X^2 + x - 6) (2x^2 + 4x) =
Let's open the brackets carefully
x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x
= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x
= 2x^4 + 6x^3 - 8x^2 + 24x
= 2x ( 2x^3 + 3x^2 - 4x + 12)

Answer:
2515 is REAL and RATIONAL
Step-by-step explanation:
π is irrational
Repeating decimals are rational.
-25 is neither a Whole nor Natural number. (Whole numbers are non-negative integers; Natural numbers are positive integers, sometimes including 0.)
Any integer or fraction is REAL and RATIONAL. 2515 is an integer, so it is ...

Answer:
The ball goes 14 meters high
Step-by-step explanation:
Given the function
y= -0.1x^2 + 2x + 4
In the figure attached, the function is shown.
The maximum height is equivalent to the vertex of the function, which is obtained as follows:
Xv = -b/(2a) = -2/(2*-0.1) = 10
Yv = -0.1Xv^2 + 2Xv + 4
Yv = -0.1(10)^2 + 2(10) + 4 = 14
Answer:
x=1
Step-by-step explanation:
3(6x-2)=-2(4x-9)+2
3(6x-2): 18x-6
-2(4x-9)+2: -8x+20
18x-6=-8x+20
18x-6+6=-8x+20+6
18x=-8x+26
18x+8x=-8x+26+8x
26x=26
26x/26=26/26
x=1
