Question

The value of the expression (5/3)x² + 1 when x = -2 ​

Answer 1

Answer:

Have buddy... Your answer is 23/3

Step-by-step explanation:

Substituting x = -2

Therefore,

(5/3)(-2)^2 +1

=(5/3)4+1

=(20/3)+1

=20/3 + 3/3

=23/3

Answer 2

Value of expression at x=-2 is 23/3 or $\bf 7 \frac{2}{3}$

Given:

• $\frac{5}{3} {x}^{2} + 1$

To find:

• Find the value of expression, when x=-2

Solution:

Put the value x=-2 in the given expression.

$= \frac{5}{3} {( - 2)}^{2} + 1$

or

$= \frac{5}{3} \times 4 + 1$

or

$= \frac{20}{3} + 1$

or

$= \frac{20 + 3}{3}$

or

$\bf \frac{5}{3} {x}^{2} + 1 = \frac{23}{3}$

Thus,

Value of expression at x=-2 is 23/3 or $\bf 7 \frac{2}{3}$.
