Hello there, and thank you for posting your question here on brainly.

Lisa is 34 years old, two years ago, she was twice as old as her brother. How old is her brother now?

Answer in short: 18

Why?

Since it was 2 years ago, you subtract 34 by 2 to get 32. Then, since she is twice as old as her brother, we divide 32 by 2, that answer is 16. That is her brother's age when it was two years ago when she was 32. We have to add back the two years to find out how old he is today. 16 + 2 is 18. He is 18 today.

Hope this helped! ☺♥

Her brother would have been 16, which is half of 32 and now he would be 18 years old

I don’t know the answer or how to do this, help!
makvit [3.9K]

Answer:

B.

Step-by-step explanation:

y = x^2 - x - 12

y = (x-4)×(x+3) that means x it either 4 or -3

y = x + 3

for x = 4 ➡ y = 3+4 ➡7

for x = -3 ➡ y = -3 + 3➡0

(the answer key is most probably faulty there's no way for y to be 0 in both scenarios)
