Question

Evaluate 5|x3-2|+7 when x=-2

Answer 1

Answer: The value of expression is 57.

Explanation:

Since we have given that

`5\mid x^3-1\mid +7`

As we have given that x = -2

So, we substitute the value of x in the above expression:

`5\mid (-2)^3-2\mid +7\\\\=5\mid -8-2\mid +7\\\\=5\mid -10\mid +7\\\\=5* 10+7\\\\=50+7\\\\=57`

Hence, the value of expression is 57.

Answer 2

57

Explanation:

5|x^3-2|+7

Let x=-2

5|(-2)^3-2|+7

Work inside the absolute values first

5|-8-2|+7

5|-10|+7

Take the absolute value, which makes it positive

5 *10 +7

Multiply

50+7

57
