Learning mathematical functions is a lot similar to learning a new language.
Like in learning a new language, its very important to work out on the relationship between words & their uses. In the same way, in functions, it is very important to understand the relationship between variables.
Firstly, a strong foundation should be built in understanding algebra. Algebra is a key to understand functions. Just like its very important to form the base foundation of syllables & basic grammar in the language.
Answer:
7x² + x – 2
Step-by-step explanation:
(4x² + 3) – (–3x² – x + 5)
First, distribute the minus sign to eliminate the parentheses (negative terms become positive and vice versa):
4x² + 3 + 3x² + x – 5
Then, combine like terms:
7x² + x – 2
Answer:
X=3
Step-by-step explanation:
12x-31=5
12x - 31 - 31 = 5 + 31
12x = 26
12x / 12 = 26 / 12
x = 3
To solve the equation you take 31 to the right by subtracting it from the left then adding it to the right.
From there you divide each side by 12

Answer:
24cm^2
Step-by-step explanation:
Given data
Length= 6cm
Width=4cm
Required
The area of the Rectangle
Area=Length*Width
Substtiute
Area=6*4
Area= 24cm^2
Let's simplify step-by-step.
7x−2+10x+x+6x
=7x+−2+10x+x+6x
Combine Like Terms:
=7x+−2+10x+x+6x
=(7x+10x+x+6x)+(−2)
=24x+−2
Answer:
<u>=24x−2</u> <----
