Answer:
Just to be on the safe side the first #1 is 31.5 and the second #1 is 57.82
X^2 and 5x both have x in common to factor out. To add or subtract them, 5x^2 is the least common denominator .
Answer:
(4t − 3) (t − 6)
Step-by-step explanation:
Using AC method:
Given a quadratic ax² + bx + c, find factors of ac that add up to b. Divide those factors by a and reduce. The denominators become the coefficients and the numerators become the constants.
Here, a = 4, b = -27, and c = 18.
ac = 4 × 18 = 72
Factors of 72 that add up to -27: -3 and -24
Divide factors by a: -3/4 and -24/4
Reduce: -3/4 and -6/1
So the factored expression is:
(4t − 3) (t − 6)
4,000. subtract the numbers, then round to the nearest thousand.
