Simplify this expression: 3(x + 4.5) + 2(2.6x – 3)

1. Distribute the 3 and 2 through the parentheses: 3(x) + 3(4.5) + 2(2.6x) - 2(3)

2. Find each product: 3x + 13.5 + 5.2x - 6

3. Combine like terms:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

i think the answer is b
