Question

Evaluate the expression below if x = 4 and y = 1.3(x + y) + 2x² + (1 + y)2

Answer 1

The given expression is:

`3(x+y)+2x^2+(1+y)^2`

We have to evaluate the expression for x = 4 and y =1. For that, just put the values of x and y in the expression.

`3(4+1)+2(4)^2+(1+1)^2`
`3(5)+2(16)^{}+(2)^2`
`15+32^{}+4`

=> 51

Hence, the answer is 51.
