Answer:
[tex]4 {x}^{3} + 2 {x}^{2} - 8x - 4[/tex]
Step-by-step explanation:
it's simple, just multiply
f.g(x)=(x^2-2)(4x+2)=4x^3+2x^2-8x-4
Step-by-step explanation:
Hi there!
f(x) = x²-2
g(x) = 4x+2
Then;
f(x).g(x) = (x²-2)*(4x+2)
= x²(4x+2) -2 (4x+2)
= 4x³ + 2x² - 8x - 4
Therefore, the answer is f(x).g(x)= 4x³ + 2x² - 8x - 4.
Hope it helps!

Answers
Answer:
[tex]\sqrt{10}[/tex]
Step-by-step explanation:
The distance between two points can be found using the Pythagorean Theorem [tex]a^{2} + b^{2} = c^{2}[/tex].
This is because, if you connected your two points with a line, that line could be defined as the hypotenuse of a right triangle. the base of that triange is the distance between the x coordinates ([tex]x_{2} -x_{1}[/tex]) and the height by the distance between the y coordinates ([tex]y_{2} - y_{1}[/tex]). Sine these are the sides of the right triangle, they are equal to a and b above (c is the hypotenuse that we are trying to find). So, we calculate the two distances above and get 3 and 1 (for x and y respectively). 3^2 + 1^ 2 =10. So the answer is square root 10.

One-third of the number is at least 5 units from 31. The number is 78.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that one-third of a number is at least 5 units from 31. The unknown number is x.
( 1 / 3 )x + 5 = 31
x + 15 = 31 x 3
x + 15 = 93
x = 93 - 15
x = 78
Therefore, one-third of the number is at least 5 units from 31. The number is 78.

Last night 30cm of snow fell in 6 hours. If it continues snowing at the
same rate, how long will it take for 45cm of snow to fall?
Answers
Answer: 9 hrs for 45cm of snow to fall
Step-by-step
If 30cm = 6 hrs
Then divide 30/6 to get the unit rate of the amount of snow per hr
Which is 5/1
So 5cm per hr
Then add 30+5+5+5 to get 45
And since we know 5cm equal 1 hr
Add the original amount of hours which is 6 plus 3 ones
Which is 6+1+1+1
In total, it will take 9 hrs for 45cm of snow to fall.
