Question

If x = 5, y = 3 and z = 2 then xz (4y - 2z) is, A. 116 B. 8 C. 80 D. 10

Answer 1

xz(4y - 2z).....when x = 5, y = 3, and z = 2
now we sub
(5*2)(4(3) - 2(2)) =
10(12 - 4) =
10(8) =
80 <==

Answer 2

The correct option is C. The value of given expression is 80.

Explanation:

The given expression is

`xz(4y-2z)`

It is given that x = 5, y = 3 and z = 2.

Substitute x = 5, y = 3 and z = 2 in the given expression to find the value of expression.

`(5)(2)(4(3)-2(2))`

`10(12-4)`

`10(8)`

`80`

The value of given expression is 80. Therefore the correct option is C.
