X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2
Hope this helped!
A number is rational if it can be written as the ratio of two integers.
The ratio of two integers is a fraction, and you just did it. Your number
is the ratio of 1 to 8 . It's about as rational as you can get.
<span>Here's a fun fact that's easy to remember:
<em>ANY</em> number that you can write down on paper, completely,
with digits
and a decimal point or a fraction bar if you need them, is
rational.</span>
Answer:
7238.2
Step-by-step explanation:
V = 
= 7238.2
The factor that multiplies with 6 to get 18 is 3 but the factor that multiplies with 6 to get 30 is 5.
The numbers in parenthesis should be a 5 and not a 10.
18 + 30 = 6(3 + 5)
Answer:
7 months
Step-by-step explanation:
We can write the equation 25x+10=185 where 25 represents the cost per month, x represents the number of months, 10 represents the sign-up fee and 185 represents the total cost.
To isolate the variable, first subtract 10 from both sides of the equation.
This new equation should look like: 25x=175
The next step in isolating the variable is to divide both sides of the equation by 25.
Doing this, you should be left with the final equation x=7 which is your answer.
