Question

Which expression has a value less than the given expression when x = 5?

3x+15
a. 2x²
b. x²+5
c. 3(x+5)
d. 4x+5

Answer 1

The expression that has a value less than 3x+15 when x = 5 is d. 4x+5.

Step-by-step explanation:

When x = 5, we can evaluate each expression to find which one has a value less than 3x+15.

a. 2x² = 2(5)² = 50

b. x²+5 = 5² + 5 = 30

c. 3(x+5) = 3(5+5) = 30

d. 4x+5 = 4(5) + 5 = 25

Out of the given options, d. 4x+5 has a value less than the expression 3x+15 when x = 5.
