Question

Find the value of given algebraic expressions when the value of ‘x’ is 4, ‘y’ is 3 and ‘z’ is 2. a) 2x + 3Y – 5 b) 5y – z +8 c) 3x 2 +y +2 d) y 3 -3 e) x 2 +y – 4z

Answer 1

Step-by-step explanation:

when

x= 4

y=3

z=2

Then,

a) 2(4) + 3(3) + (-5)

= 8 + 9 -5

= 17 -5

= 12

b) 5(3) - 2 + 8

= 15 + 8 -2

= 23 -2

= 21

c) 3x2 + y + 2

= 3(4)2 + (3) + 2

= 24 + 3 +2

= 29

d) (3)3 - 3

= 9 -3

=6

e) (4) 2 + 3 - 4(2)

= 8 + 3 - 8

=11 - 8

= 3
