Answer:
(x-3)(x^2-7) = x^3 -3x^2 -7x + 21
just change the sign of the root and put x in front of it, then multiply the factors all together
(x-3)(x-sqr7)(x+sqr7) roots come in conjugate pairs to eliminate irrational coefficients
(x-sqr7)(x+sqr7) = x^2-7. similar to (a-b)(a+b) = a^2-b^2
Step-by-step explanation:
1. Ebony's right eye....opposite of -1.50 = 1.50
2. the rational numbers are : -1.50, 1.50, -1.00, and 0.25....these are all rational because they can be turned into fractions.
3. least to greatest : -1.50, -1.00, 0.25, 1.50
4. not sure how to answer this...negatives are always less then positives....however, with negatives,unlike positives, the larger the number, the smaller it is.
Answer:
9 and 12
Step-by-step explanation:
hope this helps.
The first one is out, because it isn't fair. We want a 50/50 chance to win. If we add 2 cards with stars, then your chance of winning increases too much(as much as that'd be great). If we take away 2 blank ones, it would be fair, but we want to still have 10 cards. So the only choice left is to add a start to 1 of the blank cards.
