Question

Evaluate the expression for the given values. 2x+(3y+z*2) x= 2, y=3,z=4

Answer 1

Answer:

29

Step-by-step explanation:

$2x+(3y+z^2)\\=2*2+(3*3+4^2)\\=4+(9+16)\\=4+25\\=29$

Answer 2

Answer:

21 OR 29

Step-by-step explanation:

I can't tell whether the star symbol is supposed to be for multiplication or to signify an exponent, so just to be safe, let's solve it for both ways. :)

MULTIPLICATION

First, let's substitute the known values in for the variables:

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

Then, multiply and add:

4 + (9 + 8) = 4 + 17 = 21

EXPONENT

First, substitute known values in for variables:

2(2) + (3(3) + (4)^2)

Then, multiply and add:

4 + (9 + 16) = 4 + 25 = 29

Hope this helped!
