If you give me a great explanation to my question then I will mark ya brainliest and give you free points since this is my last day on here! I will only come on here when I need help with anything other than that I won’t be on here anymore

Hey there!

“16a = 2(a – 18)”

FIRST you have to distribute the RIGHT SIDE OF THE EQUATION

2(a – 18)

2(a) = 2a

2(18) = 36

Your RIGHT side should you like this:

2a – 36

NEW equation: 16a = 2a – 36

SUBTRACT “2a” From both of your sides!

16a – 2a = 2a – 36 – 2a

CANCEL out: 2a – 2a because that gives the value of 1

KEEP: 16a – 2a = –36 because that helps us solve for our equation

16a – 2a = 14a

NEW equation: 14a = –36

DIVIDE ”14” on your sides

14a / 14 = –36 / 14

CANCEL outS 14a / 14 because that gives you 1

KEEP: –36 / 14 because it helps us solve for your answer!

Solve above:

a = -18 / 7 ☑️

The mistake in the particular question you’ve asked , is that the person did their steps incorrectly !

Good luck on your assignment and enjoy your day!

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.
