Answer:
Here are my hints. You can solve it yourself
1/ xy = -12 --> x = -12/y
2/ (-12/y) + y = -1 --> -(12/y) + (y²/y) = -1 --> -12 + y² = -y --> y²+y-12=0
3/ From y²+y-12=0 we can find y then use y to find x and then do your
(x+3) * (y+3)
Answer:
To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.
Fraction: 9/10 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
9 = 32;
10 = 2 × 5;
gcf (32; 2 × 5) = 1;
Fraction: - 3/4 already reduced to the lowest terms.
The numerator and denominator have no common prime factors.
Their prime factorization:
3 is a prime number;
4 = 22;
gcf (3; 22) = 1;
LCM (10; 4) = 22 × 5 = 20
3/20 is the answer.........
For 27,the temp and time increase
-5 and 5.
When you multiply they equal -25.
When you add them they equal 0.
540 attempts times 30% so 540 * .30 = 162. the answer is 162.
