Question

Evaluate the expression for x = -4, y=-2, and z=-3.
x(y+z)^2?

Answer 1

Explanation:

we take the values given and we substitute in the equation above.

value of x=-4

y=-2

z=-3

hence we can solve for the equation above

-2(-2+-3)^2

we for everything in brackets first

(-2+-3)=-5

(-5)^2=25hence after solving we multiply by -2

-2(25)=-50

indeed that is my solution.

Answer 2

- 100

Explanation:

x (y + z)²

= (-4) [(- 2) + (- 3)]²

= - 4 * (-5)²

= - 4 × 25

= - 100
