You mean the 2020 ones or the ones next year. If so isnt a bit early for the 2021 SAT's?

I’m taking a math analysis course program that covers Calc I, Calc II, and probability and statistics. I find myself now reviewing math that I studied 5 years ago because my SAT is soon and I need to brush up 😂

[@tucker9929]

On question 18, the x can be mistaken for a variable, rather than a multiplication sign.

[@MathwithWaqasShah]

nice work

[@alex3256]

If you take the square root on one side of the equation, do you have to take the square root of all the numbers on the other side? Like if you have 9y=y^2+14. If I take the square root of 9y, do I have to take the square root of (+14) on the other side. Or can I just take the square root of y^2? I'm assuming not, but just want to confirm xP

[@mija1570]

Thenk you very much sir!

[@pupleshungry]

i’m really confused with question 19 can you explain how you were able to sub in 7(b/4)+25 into the square root… what was the logic… i wanna know the train of thought so i can use it during my SAT when i con across a question like that

[@cesarl9670]

Nice

why does question 17 have 'd = 3' ?? if theres no such thing in the eqn or if theres no need for it..

[@nil-md2ef]

i was looking for an answer to exact same question lol

[@SxmieEsports]

y-d

[@alvinwright4311]

Umm sir, is there an easier way to solve this problem (the first one)? The step is kind of long

[@Dyutube13]

Use squaring both sides. It’s easy

[@catlvrzz]

can’t i just divide 8 by 4 in the end ? 😭

[@Rabits52]

Man i didnt see the last question because of his subs
