Answer:
3x^3 + 6x^2
Step-by-step explanation:
2x^2 + 3x^3 + 4x^2
Combine like terms
3x^3 + (2x^2+4x^2)
3x^3 + 6x^2
Answer:
b. 6 x² + 4 x³
Step-by-step explanation:
2x ² + 3x³ + 4x²
Combine like terms, we get
2 x² + 4 x² + 3 x³
6 x² + 3 x³
option a and b both are similar.
Answer:
(8+2) and (9+1) is the most fastest adding pair.
Step-by-step explanation:
It is easy to add zero digit number here it will be
We can club the two number or we can club two pair so as to form 10 in each of the pair
It will be (8+2) which gives 10
And (9+1) which gives 10
And it will very easy and fast to add 10 + 10
Rather than any other pair.
An expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context. The value of x makes this proportion true 3/x=15/40 is 8.
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
A ratio shows us the number of times a number contains another number. The value of x in the given expression can be found using the ratios. Therefore, The value of x makes this proportion true 3/x=15/40 is,
3 / x = 15 / 40
3 × 40 = x × 15
120 = 15x
x = 120/15
x = 8
Hence, The value of x makes this proportion true 3/x=15/40 is 8.

Answer:
Step-by-step explanation:
The direct variation is defined as
where, k is constant of proportionality.
It is given that a direct variation function contains the points (-8,-6) and (12, 9).
Substitute x=-8 and y=-6 in the above equation.
Divide both sides by -8.
The value of constant of proportionality is . So, the required equation is
At x=12,
It means, the line passing through (12,9). Hence, the equation is correct.
Therefore, the equation of the function is .
