Answer 1
Answer:

Answer:

Option (b) is correct.

Step-by-step explanation:

Given: Polynomial 2x^3-5x-1 and 4x^3+8x+3

We have to find the sum of given polynomial and choose the correct option from given options.

Consider the given Polynomial 2x^3-5x-1 and 4x^3+8x+3

We have to find the sum that is 2x^3-5x-1+(4x^3+8x+3)

Apply plus minus rule +(-a)=-a

We have,

2x^3-5x-1+4x^3+8x+3

Now adding like terms, we have,

Like terms are terms having same variable with same degree.

(4+2)x^3+(8-5)x-1+3

Simplify , we have,

6x^3+3x+2

Thus, option (b) is correct.
Answer 2
Answer: (2x3 − 5x − 1) + (4x3 + 8x + 3)
=6x^3 +3x +2

answer is  b. 6x3 + 3x + 2

Okay so im really not in the mood sorry not worth that much points and hopefully you slept well and stuff like that but anyways thanks :)8 x 4 x 6 x 9 x 3 x 10 + 25 + 68 = ?

Answers

8 x 4 x 6 x 9 x 3 x 10 = 51,840
Now add our 25 and 68 to the total. 
51,840 + 25 + 68 = 51,933

Therefore your answer is 51,933

By the way this was a really easy question again you should message me instead of using that many points!  

love, the Pineapple.

25+68=93

8 x 4 x 6 x 9 x 3 x 10 = 51840

51840 +93 = 51933

I hope this helps=)

If you vertically stretch the quadratic parent function, f(x) = 2^x, by a factor of 3, what is the equation of the new function?

Answers

If you stretch on the y-axis then you are increasing/decreasing values at a every x.

The new function is therefore:

g(x)=3\cdot2^x

Answer:

the stone fell in the air for 7 sec and fell in the water for 5 sec

Answer:

Let time taken in air be 'a'

And the time taken in water be 'b'

a+b=12

Distance covered in air = 16a

′′′′′ ′′″″ water= 3b

16a + 3b = 127

Solve the two equations simultaneously

a= 7 secs

b= 5 secs
