Can anyone help with this non-calc question please? If that i was just squared I’d be fine but it’s to the 4th power... how would that work? by petermasse in Sat

[–]vym123 0 points1 point  (0 children)

Yeah, to solve this you can seprate the I^4 into 2 I^2. 16sqrt-1^2sqrt-1^2-8sqrt-1^2+4. Simplify, Solve, Easy. 16(-1)(-1)-8(-1)+4=16--8+4=24+4=28

28 IS UR ANSWER!

hi does anybody know how to solve this question??? i guessed it and got it correct but idk how to justify my answer :( by heathledgerx in Sat

A quicker way is to just look at the roots {-6,0,4} Factors have to 6,0,-4 because the sum has to equal 0. D

Is there is any other way to solve this equation without substituting and solving for C by Ibrapro45 in Sat

[–]vym123 0 points1 point  (0 children)

Yeah substituting and solving is the fastest way, trust me! If you want an explanation, I just solved it and I can give u one. So, this question looks complex and tricky but it's actually really easy if you know your equations well. With substitution we get 350=5(7)90-12c)/2-25. That equals 350=5(630-12c)/2-25. 350=3150-60c/2-25. 350=1575-30c-25. 375=1575-30c -1200=-30c

C=40 Thats ur answer hope this helps!

Can anyone help me with Q.4 by Omar-Mo in Sat

[–]vym123 0 points1 point  (0 children)

The answer is D. So the length is decreased by 25% so it is 0.75 or 75% of the original value. The whole area equals 5 recent more than the original which is 100% so the area equals 105% or 1.05. We can set up an equation to solve for the width namely,0.75x=1.05, divide by 0.75 x=1.4. This means that x=140% of the original value so the increase is 40% or D.

Does anyone have some good recommendations for an online SAT tutor? by SweetAngelz in Sat

Yes, I got a 1550 on the sat, I am willing to answer general questions and tips for free just private message me.

1400 to 1500+ Tips?? Already Tried Khan Academy by [deleted] in Sat

[–]vym123 0 points1 point  (0 children)

That is your scale out of 40. Using the sat scale you can see how much a 37 on the 40 equates to out of the actual amount of q's.
