4. If BÉ is a perpendicular bisector of AD, which statement is true?

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.

The answer is a (-3,-10.75

Do you have answers choice but i think the answer is 18 because 2/3 times 18 =12 serving hope this can i have brinlyest
