Question

If x=2 ,y=5 calculate 3xy+2y²-3x

Answer 1

Step-by-step explanation:

3xy+2y²-3x

2y²-3x+3xy

x= 2

y=5

then

2(5)²-3×2+3×2×5

2(50)-6+30

100-6+30

130-6

=124

Answer 2

Here we are given an expression 3xy+2y²-3x.

We have to find the value of the expression.

value of x and y are given

x = 2

y = 5

We will put these values in the expression

3xy+2y²-3x = 3(2)(5) + 2(5)² - 3(2)

= 30 + 50 - 6

= 80 - 6

= 74

so, the value of 3xy+2y²-3x will be 74.
