Question

Find the value of the expression 2x3 + 3y2 − 17 when x = 3 and y = 4. 26 85 943 1,927

Answer 1

B. 85

Explanation:

We have been given an expression
`2x^3+3y^2-17`. We are asked to find the value of expression, when
`x=3` and
`y=4`.

To find the value of our given expression, we will substitute
`x=3` and
`y=4` in our expression as:

`2(3)^3+3(4)^2-17`

`2*27+3*16-17`

`54+48-17`

`102-17`

`85`

Therefore, the value of expression at the given values would be 85.

Answer 2

85

Explanation:

2x^3 + 3y^2 − 17

2(3)^3 + 3(4)^2 − 17

2*27 + 3*16 -17

54 + 48 -17 = 85
