Answers

Answer 1
Answer:

Answer:

\large\boxed{(3a+2)(4a^2-2a+9)=12a^3+2a^2+23a+18}

Step-by-step explanation:

(3a+2)(4a^2-2a+9)\qquad\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\n\n=(3a)(4a^2)+(3a)(-2a)+(3a)(9)+(2)(4a^2)+(2)(-2a)+(2)(9)\n\n=12a^3-6a^2+27a+8a^2-4a+18\qquad\text{combine like terms}\n\n=12a^3+(-6a^2+8a^2)+(27a-4a)+18\n\n=12a^3+2a^2+23a+18

Convert 11.42424242 … to a rational expression in the form of a over b, where b ≠ 0.

Answers

Answer:

x  = (1131)/(99).

Step-by-step explanation:

Given  : 11.42424242 …

To find : Convert it to a rational expression in the form of a over b, where b ≠ 0.

Solution: We have given 11.42424242 …

We can see here two number 42 are repeating.

Let x = 11.42424242 …

On multiplying both sides by 100

100x = 100 * 11.42424242 …

100x = 1142.424242.....

100x = 11.4242.....+1131.00000.....

100x = x + 1131.0000....

On subtracting both sides by x

100x -x = 1131

99x = 1131.

On dividing both side by99.

x  = (1131)/(99).

Therefore, x  = (1131)/(99).

11.42... = 11 42/99 = 1131/99 reduces to 377/33

Find the distance between the pair of points . (-3,-6) and (-3, 1)

Answers

Answer:

7

Step-by-step explanation:

add 6 to -6 to get 0

than add 1 to 0 to get 1

6+1=7

Final answer:

The distance between the points (-3,-6) and (-3, 1), both lying on the same vertical line, is found by subtracting their y-coordinates. The distance is 7 units.

Explanation:

The subject of this question is in the field of Math, specifically focusing on the concept of distance between two points in a plane. In this case, you are asked to find the distance between the points (-3,-6) and (-3, 1). The calculation is very straightforward as both points lie on the same vertical line where the x-coordinate of both points is -3. To find the distance between two points which lie on the same line , we can simply subtract the two y-coordinates.

So, the distance is given by the absolute value of the difference between the y-coordinates: |1 - (-6)| = |1 + 6| = |7| = 7.

So, the distance between (-3,-6) and (-3,1) is 7 units.
