Answer:
3(x+y)+15xy
Explanation:
Write an algebraic expression for the verbal expression: three times the sum of X and Y increase by five times the product of x and 3y.
Sum of x and y = x+y
three times the sum of X and Y = 3(x+y)
product of x and 3y = x(3y) = 3xy
five times the product of x and 3y = 5(3xy) = 15xy
Three times the sum of X and Y increase by five times the product of x and 3y will be expressed as;
3(x+y) + 15xy
Hence the required algebraic expression is 3(x+y)+15xy
