My grandson had this homework, badly worded question or just go with the obvious for a 7 year old?

lol sorry

Is this some mathematical property i need to know? Or just pure meme..

It is also solved the memo way when I googled the answer.

It looks nonsensical to me. The notation doesn't even seem to be used correctly. It's even got an odd number of parentheses!

I’m trying it for days

Found this on Facebook and theres 3 methods used primarily but the answer is either t is zero or its unsolvable

Someone please put me out of my misery, I can't figure it out!

Here is the question. I picked the last option (5th).

If it's true is there any proof. I came upon this question when I was solving a problem which required using similarity of triangles.

Forgot to put the tick marks on but it is a square/ equal side lengths

Saw this interesting and impossible geometry question in Instagram. The method I use is similar triangles. I let height of triangle (what the qn is asking) be x. The slighted line for the top left triangle is (x-6)² + 6² = x² - 12x + 72. Then, x-6/6 = √(x² - 12x + 72)/20. After that, I'm really stuck. I appreciate with the help, thanks.

This might make me look like an idiot but bear in mind I haven’t done maths since grade 10 in high school and I don’t know whether im lacking in common sense or not, but I’d appreciate your help.

I’m doing an online practice assessment for a retail job and this question keeps confusing me. I thought that the answer would be $232.16 after 10% of discount but for some reason that’s not even an option and I had to press on all the answers to figure out which one was right.

Can someone please explain how they got $212.95?

Thanks!!

I’m helping someone study for their Standard Grade exams and was trying to solve this. I could do it easily with calculus, but she won’t learn that until next year. What other methods can be used to solve it?

Yes, maybe they're just joking with me but I would still like to know how to explain it clearly and concisely.
