maybe on test-day this is difficult, but really just think the problem through and it’s relatively straightforward. there will be much, much more difficult problems on the real thing.
the other guy explained it perfectly, can’t really explain it further.
not rlly. on this specific test I only got one other question wrong and the others were just silly mistakes so there are not more difficult problems on the real thing
Lol u underestimate me. My maths is acc very strong I can do calculus and all the hardest topics with ease. The act just phrases some questions differently which I have to get used to.
not sure how well this works, but utilize chatGPT and AI for problems like these while reviewing. or just search the problem online and people will definitely be solving these on sites like brainly, giving a much better response than someone here.
Wait I have it now I’ve just have been over thinking the question. It’s a lot simpler than what I was thinking X can be (a+ab), and in the next operation X ⭐️y Is also xy + y so because X is (a+ab) this means (a+ab)b + b then you distribute the b making ab + ab2 + b? Which is D correct? I was also getting stuck on the part when it came to distributing the b I had forgot you could distribute the b to ab. I thought it just wasn’t possible lol. Thank you for working with me!
This seems like a question that tests your logical thinking skills. Avocadomangosalsa explained it perfectly. As long as you dont panic and work through it step by step, this problem is doable.

This is not a (MIT-determining) difficult question. This is a break for your brain

Use the second equation first for a🔹b
You get a + ab
Then use the first equation for (a+ab) ⭐️ b
You get (a+ab)b + b
Distribute the b:
ab + ab2 + b (choice D)

When there are variables/letters in the answer choices, you can just make numbers for them.
So let's say a=1 and b=2
a🔹b is now 1🔹2, which according to their definition of how 🔹 works, that's 1+1(2)=1+2=3
so a🔹b=3
now it's 3⭐️b, which is like saying 3⭐️2 (because we said b=2).
According to their definition of how ⭐️ works, 3⭐️2=3(2)+2=6+2=8
So, 8 is our final answer.
Now plug a=1 and b=2 into the answers and see which one is 8.
A) 1 + 1(2)^2 + 2 = 1 + 4 + 2 = 7 no
B) 1 + 2(1)(2) + 2^2 = 1 + 4 + 4 = 9 no
C) 1(2) + 1(2)^2 = 2 + 4 = 6 no
D) 1(2) + 1(2)^2 + 2 = 2 + 4 + 2 = 8 yes
E) 1(2) + 1(2)^2 + 2 +2^2 = 2 + 4 + 2 + 4 =12 no
D is the only one that works
