For this case we have the following expression:
The terms are not similar, so they cannot be added.
<em>Examples of similar terms:</em>
Then, the expression given can only be rewritten as:
This is taking common factor 2 to both terms.
Answer:
Answer:
(s*t)(-7) = 987
Step-by-step explanation:
s(x) = 2 - x²
t(x) = 3x
To find (s*t)(x), multiply s(x) and t(x).
(s*t)(x) = (2 - x²)(3x)
(s*t)(x) = 6x - 3x³
Now that you have (s*t)(x), plug -7 in.
(s*t)(-7) = 6(-7) - 3(-7)³
(s*t)(-7) = 6(-7) - 3(-343)
(s*t)(-7) = -42 + 1029
(s*t)(-7) = 987
-4x - 6 = 10
To solve the equation, you will have to isolate the x. Because of the equal sign, what you do to one side, you do to the other.
-4x - 6 = 10
Do the opposite of PEMDAS. First add 6 to both sides
-4x - 6 (+6) = 10 (+6)
-4x = 10 + 6
-4x = 16
Isolate the x, divide - 4 from both sides
-4x/-4 = 16/-4
x = 16/-4
x = -4
-4 is your answer
