4(x^2 - 5) + 2(3x^2 + 6)
Answers
Answer:
=10x2−8
Step-by-step explanation:
4(x2−5)+2(3x2+6)
Distribute:
=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)
=4x2+−20+6x2+12
Combine Like Terms:
=4x2+−20+6x2+12
=(4x2+6x2)+(−20+12)
=10x2+−8
The process is in the picture down below.

What is an expression?
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the ribbon size is 5(¹/₃) and the piece to be cut is 2/ 3 feet in size.
The number of pieces will be calculated by dividing the total size by the per piece size.
N = [ 5(¹/₃) / ( 2/ 3) ]
N = [ (16/3) / (2 / 3)]
N = 16 / 2
N = 8
Therefore, the number of pieces will be equal to 8.

You justify a step the same way you decided to go through with it:
Remember a rule, axiom, postulate, theorem, or corollary you learned
that says it's a legal thing to do.
Like if you thought of erasing one of the terms in an equation because
that would make the rest of the equation easier to work with, you would
not do that, because no book or teacher ever said that it was legal.
Or if you thought of adding 42 to both sides of an equation, you could
do that, because you learned that "If equals are added to equals, then
the results are equal". Then later, if anybody ever asked you why you
could do that, or asked you to justify your step, you'd tell them the same
statement.

Okay, let's see...
The problem is asking for a linear equation most likely in the form of y=mx+b
y is another way to say f(x)
m = slope
b = y intercept
Let's start with the y intercept first.
Y intercept means ' When does the line touch (intercept) the y axis.
In this case, if you look at the graph, the line touches the y axis at -1.
-1 will replaces b
To find the slope we are going to take 2 precise points from the graph.
Lets use (0,-1) and (-6,4)
To find the slope, we're going to use
4 - (-1) / -6 - 0
Solve, our slope is 5/-6
That is our m
Our final equation is
