Answer:
Solutions to the equation are 
which agrees with the last option listed among the possible answers
Step-by-step explanation:
We solve this quadratic equation via the quadratic formula:
Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0
Answer:
7(w + 5)(w -5)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
7w² - 175 = 7w² - 7*25
= 7(w² - 25)
= 7(w² - 5²)
= 7(w + 5)(w -5)
Answer:
44
Step-by-step explanation:
In other words, the minute hand "overtakes" the hour hand on 44 occasions in 24 hours in order to give a 90 degree angle. Therefore the answer to your question is 44.
