Evaluate the expression (2x + y) +5 when x = 4, y = 10.

23

Step-by-step explanation:

The question is a under substitution, that's a given number will be used to replace a letter

So back to the question

(2x+y)+5

And x is said to be 4 and y is 10

Let's start solving

(2(4)+10)+5

Hope you understand it to this extent,any where you see x you will have to put the given value for x same goes for y

(8+10)+5

18+5

23

Therefore the evaluation is 23

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
