Question

Remember to follow order of operations & combine like terms!

3⋅15+4⋅15−5⋅15


3x+4x−5x

3(x−2)+4(x−2)−5(x−2)

Answer 1

Following the order of operations and combining like terms, we get:

3⋅15+4⋅15−5⋅15 = 45 + 60 - 75 = 30

And for the second expression, factoring out the common factor (x-2) and simplifying, we get:

3(x-2) + 4(x-2) - 5(x-2) = (3+4-5)(x-2) = 2(x-2) = 2x-4
