To make this easier, rewrite the equation in descending order:
x^{2} + 5x = 36
Then, move everything to one side by subtracting 36 from either sidex^{2} +5x-36=0
Next, factor the equation into two binomials:
(x+9)(x-4)=0
Then, split the two binomials and set them both equal to zero.
x+9=0;x-4=0
Then, simply, solve for x by isolating it:
(x+9)-9=0-9;(x-4)+4=0+4 \\ x=-9;x=4
Your two answers are x=-9 and x=4

If you're interested, you can check both answers by plugging them into the equation. 

Hope this helps!

G(r)=−5r+13<br> g(3)=<br><br> I'm still confused on how to do this
SashulF [63]

If you're solving for g then move all terms to the left side and set equal to zero. Then set each factor equal to zero.

And your answer becomes g=\frac{5r}{r-39}

If you're solving for r then then move all terms to the left side and set equal to zero. Then set each factor equal to zero and your answer is r=\frac{39g}{g-5}

Somebody please help! posted picture of question
Neko [114]
Answer:
3x² - 2x - 6

Explanation:
We are given that:
f (x) = 3x² - 2
g (x) = 2x + 4

We want to find the value of (f - g)(x), this means that we will simply subtract g (x) from f (x) as follows:
(f - g)(x) = f (x) - g (x)
(f - g)(x) = 3x² - 2 - (2x + 4)
(f - g)(x) = 3x² - 2 - 2x - 4
(f - g)(x) = 3x² - 2x - 6

Hope this helps :)

134 A financial analyst believes that if interest rates decrease in a given period then the
lawyer [7]

The probability that the market will go up and interest rate will go down during the period in question is 0.03.

<h3>What is the probability?</h3>

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability that the market will go up and interest rate will go down  = 0.08 X 0.40 = 0.03

Add or subtract the polynomials
Mashcka [7]

Answer:

7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.

On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.

For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.
