Answer:
the anser is 1046.265 because in
492.36=12hour
? =51/2hour then criscros both side 492.36*25,5/12=492.36
(−7a − 19c) − (−12a + 30c) − (−21a − 11c)
= −7a − 19c + 12a - 30c + 21a + 11c
= (-7a + 12a + 21a) + (11c - 19c - 30c)
= 26a - 38c
= 2(13a - 19c)
Answer:
Step-by-step explanation:
The first thing that can help you here is factoring every term.
Factor.
Factor.
18p
Factor, keeping in mind the denominator of the other term.
Factor.
Now you have simplified your original problem:
into:
Now, after multiplying the numerator and denominator of the fractions:
Then, you can simplify the fraction by cancelling terms:
Hope it helps :) and let me know if you want me to elaborate.
The another way to write (s - 6)(s + 1) is s² - 5s - 6
Step-by-step explanation:
Let us revise how multiply two binomial (a + b)(x + y)
- Multiply the 1st terms
- Multiply the 2nd terms
- Multiply the nears and extremes, where nears are the 2nd term of first bracket and 1st term in the second bracket, the extremes are the 1st term in the first bracket and the 2nd term in the second bracket
- Add the like terms if necessary
∵ The area of the square = (s - 6)(s + 1)
- To find the another way multiply the two brackets
∵ s × s = s²
∵ -6 × 1 = -6
∵ -6 × s = - 6s ⇒ nears
∵ s × 1 = s ⇒ extremes
- The terms - 6s and s are like terms, then add them
∵ - 6s + s = - 5s
∴ (s - 6)(s + 1) = s² - 5s - 6
∴ The area of the square = s² - 5s - 6
The another way to write (s - 6)(s + 1) is s² - 5s - 6

Answer:
Step-by-step explanation:
To answer this, look at the form of the answer. they want miles per hour. So, just do that calculation
She traveled 14 miles in 6 hours.
14 miles/6 hours
14/6 = 7/3 = 2.3333 miles/hour
