Answer:
(2x - 5) • (x + 3)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 2 • -15 = -30
Step-2 : Find two factors of -30 whose sum equals the coefficient of the middle term, which is 1 .
-30 + 1 = -29
-15 + 2 = -13
-10 + 3 = -7
-6 + 5 = -1
-5 + 6 = 1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and 6
2x2 - 5x + 6x - 15
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (2x-5)
Add up the last 2 terms, pulling out common factors :
3 • (2x-5)
Step-5 : Add up the four terms of step 4 :
(x+3) • (2x-5)
Which is the desired factorization
Final result :
(2x - 5) • (x + 3)
The solution is....................
Answer:
Total cost= $760
Step-by-step explanation:
Giving the following information:
Number of students= 347
Each bus holds 44 students.
Bus cost= $95
<u>First, we need to determine the number of buses needed:</u>
Number of buses= total students / student per bus
Number of buses= 347 / 44
Number of buses= 7.88 = 8 buses
<u>Now, the total cost:</u>
Total cost= 8*95
Total cost= $760
Answer:
Answer: (2a - 5 + b)5

Answer: (-2a + 5 - b) ⋅ (-5)
Answer:
700n + 300
Step-by-step explanation:
We know that no matter what happens, Sarah has to pay a One-Time $300 for her deposit.
Now, we know that for every month she stays in the apartment, it will cost her $700.
So, we can come up with a formula to find out how much she would pay:
700n + 300
Hope this helps!
