Enrollment at X = 0 is at 20.
Enrollment at X = 8 is 120.
Find the difference between those values:
120 - 20 = 100
Divide that difference by the difference in the x values:
100 /8 = 12.5
The answer is D. 12.5
Answer:
length and width=4
height=8
Step-by-step explanation:
Hello to solve this problem we must propose a system of equations of 3x3, that is to say 3 variables and 3 equations.
Ecuation 1
Leght=Width
.L=W
Ecuation 2
To raise the second equation we consider that the length and width of 4 inches less than the height of the box
H-4=W
Ecuation 3
To establish equation number 3, we find the volume of a prism that is the result of multiplying length, width, and height
LxWxH=128
From ecuation 1(w=h)

solving for H

<em />
<em>Using ecuation 2</em>
H-4=W

Now we find the roots of the equation, 2 of them are imaginary, and only one results in 4
W=4in
L=4in
to find the height we use the ecuation 2
H-4=W
H=4+W
H=4+4=8
H=8IN
Answer:
<em>B) One sheet of paper is 0.0042 inches thick</em>
<em></em>
Step-by-step explanation:
All the other values are not give from just a sheet of paper, and/or they are either a cumulative value, or values that will be used to calculate another value
Only option B defines a value for a unit of paper, and the value is definite.
Option A indicates the number in a group (gross)
Option C shows two values that can be used to calculate one value; the area.
Option D indicates an accumulated value of weight.
Answer:
(x+3)(x+3)
Step-by-step explanation:
1) this polynomial is in the form of ax^2+bx+c
c=9
b=6
a=1
what*what=c(9)
and what+what=b(6)
3 is the answer to both questions:
now substitute "3x" in place of "6"
x^2+3x+3x+9
split in 2 groups:
group a) (x^2+3x)
gcf of group a=x
x(x+3)
group b) (3x+9)
gcf of group b=3
3(x+3)
combine the numbers OUTSIDE the parantheses
so
(x+3)(x+3)
To write an expression, you need operators such as -,+,or *. You will also require numbers, or in algebraic cases, variables. Two expressions that equal each other are considered <em>equations</em>. Know that <em>expressions</em> do not have equal signs, this is what separates them from a standard <em>equation</em>.
Some examples of expressions:
2 + 5
3 - 2
10 + 4
Some examples of equations
2 + 3 = 4 + 1
9 - 3 = 5 +1
2 * 10 = 5 + 15
