An easier way to do q18:

I initially tried to do it the way you did, but I wasn't able to do (24)^2 +(18)^2 = c^2 in time.

An easier way to do it is by realizing that 18/6 = 3. You can easily find the hypotenuse of the smaller triangle which ends up being 10, and you can multiple that by 3 to get 30.

You're a GOAT btw. Would be totally screwed without these vids.

Im from Puerto Rico and I need to get the SAT in march and you videos help me a lot to practice the math exercises. Thank you.

Literal genius, thanks so much for this!

Mister as for number 18 we could just use the special and similar triangles ... 6 became 18 so multiply by 3, 8 * 3 =24 so now we use the special triangle 3, 4, 5 the smaller one is multiplied by 2 which is how 3 became 6 and 4 became 8 so the hypotenuse is 10 then 10*3 =30

For question 19 can you explain how you set up that equation

[Aon...]

watching this again, For Q16, there is an easier way to solve especially if you've taken Calc AB or pre-calc(don't quote me on this). You can rewrite a^(b/4) as the fourth root of a^b which you then can use simple algebraic methods in order to see that a^b = 16^4 thus 4 is one possible solution. This is quicker as it doesn't involve brute force and trial and error but I don't recommend especially if you haven't taken any kind of advanced mathematics.

Heyy, could you please explain why in question 19 the equation is set up like: 0.15 ( 3 + x )?? thank you!

[roqeeb]

Which video should I watch to get a better grasp of question 9

[nwshiar]

Really helpful man. Keep up the good work

[rawanel-doumani]

Mister, would you please make a video based on the synthetic division ??

[MasterWoozAngelz]

hii !! at 22:20 once we find out that BA is 24, why don't we plus 24 and 8 then square do pythagorus using 32 and 18?

[gabrielazimi]

question 19 could you explain it better i didnt really get how u set up that equation

[bullwinklemoose]

For question 10 I don’t understand why you divide it by 4 and not 3

[kattievids]

Damn 20/20? how smart are you? I think i would get as 12/20 maybe. or 13/20 don't remmember! Math is not my strong suit ....
