Factor the equation x^2-3x-18
Answers
Answer:
This is a Non-Perfect Square Trinomial. To factor this type of trinomial, you have to remember this pattern:
So you need to find two numbers such that the product is
and the middle term is the sum
. From our polynomial:
Those numbers are:

4 hours and 25 minutes before 2:95 am would be 9:40pm
Answer:10:20 pm
Step-by-step explanation:
Time is seperated into 2 sets of 12 hours, am and pm; and 24 hours with each being 60 minutes. AM is morning and PM is afternoon.
The question is what time is 4 hours and 25 minutes before 2:05 in the afternoon. This means you subtract.
205 - 425= -220
Then, because it is negative, you change it from am to pm and subtract 220 from 1200=
1200-220=980
9:80 is has too high a number in the minutes section (the second part) so you see how many sets of 60 are in 80. There is one set of 60 meaning there is one hour added to the hour side (the left side):
9+1: 80-60
10:20
10:20 pm is the final answer.

Like I said on the other question. Slope will ALWAYS be the number beside x and y-intercept will always be after that.
Slope-intercept form = y = mx + b
Slope goes where m is and y-intercept goes where b is.

A. 3(J + 15) = J - 1
B. J + 15 = 3J - 1
C. J + 15 = 3(J - 1)
Answers
If J represents John's age, then J + 15 = 3(J - 1) equations could be used to solve the problem
What is Equation?
Two or more expressions with an equal sign is called as Equation.
Given that
"I am 3 times as old as Sue is," Frank said to Ann. "On the other hand, I am 15 years older than John while Sue is 1 year younger than John.
F=Frank
J=John
S=Sue.
I am 15 years older than John
In the sense Frankes age is 15 more than John age, So it is 15+J
Sue is 1 year younger than John.
So Sue's age is less than john
J-1
"I am 3 times as old as Sue is"
Three times of J-1
3(J-1)
So equating this we get
Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.
15+J=3(J-1)
Hence 15+J=3(J-1) is the equation could be used to solve the problem.

Frank = F
Sue = S
John = J
F=3*S
F = J+15
S = J-1
If you want to find Frank's age, then his age would be equivalent to John's plus 15 years.
A.-Would not work because Frank is three times Sue's age, not John's (left hand side of the equation).
B.-Notice that the right hand side of the equation is equivalent to Sue's age, which we know is John-1, however it is currently written to be "three times Sue's age minus one" which would give us John's age, plus two more years than his actual age on the left hand side.
C.-Frank's age is equal to John's plus fifteen (right side of the equation) and Frank is equal to Sue's age times 3. But, if Sue is in terms of Johns, then Sue's age is John's minus one. Therefore, Frank's age is equal to three times Sue's age of John minus one, which is the left-hand side of our equation.
Therefore C is the answer. C:
