A) find the value of 2x+y wehn x =4 and y =3 b) find the value of a^2 + b when a = -2 and b = 5

Reil [10]

Answer:

Solution,

a. Given,

X=4

y=3

Now,

 $2x + y \\ = 2 \times 4 + 3 \\ = 8 + 3 \\ = 11$ 

b. Given,

a=-2

b=5

Now,

 ${a}^{2} + b \\ = {( - 2)}^{2} + 5 \\ = 4 + 5 \\ = 9$ 

hope this helps...
