Choose the correct sum of the polynomials (3x3 − 5x − 8) + (5x3 + 7x + 3).8x3 + 2x + 5
2x3 − 12x − 11
2x3 + 12x − 5
8x3 + 2x − 5

Answers

Answer 1
Answer:

The sum of the polynomials are  8x^(3)+2x-5

Summation of Polynomials:

To find the sum of polynomials we have to add like terms.

Like terms are those terms which have same variable with same exponent power.

Given polynomials are,

                     (3x^(3)-5x-8 )+(5x^(3)+7x+3 )\n\n=3x^(3)+5x^(3)-5x+7x-8+3\n \n =8x^(3)+2x-5

Answer 2
Answer:

Answer:

Sum of the polynomials is 8x^3+2x-5

D is the correct option.

Step-by-step explanation:

The given polynomial is (3x^3-5x-8)+(5x^3+7x+3)

Distribute plus over the parenthesis

3x^3-5x-8+5x^3+7x+3

Group the like terms.

3x^3+5x^3-5x+7x-8+3

Combine the like terms

8x^3+2x-5

Hence, the sum of the polynomials is 8x^3+2x-5

D is the correct option.

Answer:

w = 24

Step-by-step explanation:

(5w)/(8) = 15

Multiply both sides by 8.

5w = 15 × 8

     = 120

Find w.

w = 120 ÷ 5

w = 24

Hi guys can u please help and doing hw and i don't understand.

Answers

Answer:

C

Step-by-step explanation:

The weight of the weight lighting bar = the initial value/y-intercept (b) = 45

Amount of weight = x

Total amount of weight = y

The rate of change (m) = 1

Thus to write the function that models this situation, substitute m = 1, and b = 45 into y = mx + b

Thus:

y = (1)x + 45

y = x + 45

The correct option is c
