No to all the above

math
L=7W 2L+2W=72 2(7W)+2W=72 14W+2W=72 16W=72 W=4.5, now substitute that back in either original equation to solve for L and L=31.5 Substitute in both original equations, both work.

Maths- Discriminants
The discriminant is b^2-4ac. For more information, check out this website; it's very helpful. h t t p : / / w w w . r e g e n t s p r e p . o r g / R e g e n t s / m a t h / a l g t r i g / A T E 3 / d i s c r i m i n a n t . h t m

2(x-3)-17=13-3(x+2) 2x-6-17=13-3x-6 2x-23=7-3x 2x=30-3x 5x=30 x=6

Algebra 2
I'll be honest, I don't know if you are right in the beginning. I can, however, tell you how to continue from 4x^2=100, if you are right up until that point. 4x^2=100 Divide both sides by 4. x^2=25 Take the square root of both sides. x=+-5

It's one of the variables, but I'm not sure which.

The discriminant is b^2-4ac, or the part behind the square root in the quadratic formula. Try this website for more info. h t t p : / / w w w . r e g e n t s p r e p . o r g / R e g e n t s / m a t h / a l g t r i g / A T E 3/ d i s c r i m i n a n t . h t m Without the spaces...

A fact is something that can be proven to be true. Examples: the sky is blue, 12*10=120, the capital of NJ is Trenton. We can check on any of these things if we do not know. An opinion is something that cannot be proven. Examples: blue is the best color, that shirt is nice. (O...

Please do not repost questions. Many tutors will choose to ignore your questions if you do this.

Yes, it is closed because if you multiply any of those numbers by any of those other numbers, you will always get one of the numbers in that set.

3 3/5 gallons is how much water you drank after 6 days. 6 days * 3/5 gallons each day is 3 3/5. BUT..the question is how much water is left. If you started with 5 gallons, now you must do 5-3 3/5 for your answer.

Adding doubles is the same thing as multiplying by 2. Instead of memorizing the two tables, all you have to do is add the same number twice. Examples: 4*2=4+4=8, 7*2=7+7=14, etc.

Is this a triangle? If so, all 3 angles add up to 180 degrees. 180-(31+121)=?

the question is there

Exactly 3 is impossible. If 3 were right, 4 would have to be right. The chances of exactly 3 would be 0.

You have to divide. 3000/270000=90 (because 3/27=9 and you can cancel 3 zeroes from the top and bottom which leaves one zero). 90/63000=700 (9/63=7 cancel 1 zero from the top and bottom and you have 2 zeroes left)

I agree. There should be consequences for actions, so that people cannot do whatever they want. The world would be in total chaos if everyone did what they wanted to when they wanted to. What do you think?
