Manufacturing a company is designing a new rectangular shipping box that must have a
volume of 24 cubic inches. The company has created a box with a width that is 2 inches less
than its length. The height is 5 inches greater than the length. What are the dimensions?
Answer:
3in by 1in by 8in
Step-by-step explanation:
Volume of the box = Length × Width × Height
Given
Volume = 24in³
If the width is 2inhes less than the length
W = L-2... 2
Also if the height is 5 inches greater than the length, then;
H = L+5 ... 3
Substitite 2 and 3 into the formula.
V= LBH
24 = L(L+5)(L-2)
24 = L(L²+3L-10)
24 = L³+3L²-10L
L³+3L²-10L-24 =0
Factorize
The factored form is
(L+2)(L²+L−12) = 0
L²+L-12 = 0
L²+4L-3L-12 = 0
L(L+4)-3(L+4) = 0
(L+4) = 0 and L-3 = 0
L = 3in
W = L-2
W = 3-2
L = 1in
H = L+5
H=3+5
H = 8in
Hence the dimension is 3in by 1in by 8in

Ω
Answer:
The triangles are similar as the ratio of their corresponding sides are equal
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal
As we can see, 85 is between 10 and 18
The ratio of the numbers will be ;
10/18 and 25/45
To the simplest terms;
5/9 and 5/9
Since the ratio is equal, then the triangles are similar

The endpoints of CD are C(-2,-4) and D(6,2). What are the coordinates of the midpoint of CD?
The coordinates of the midpoint of CD is [tex](2, -1)[/tex].
What is a midpoint?"The midpoint of a segment can be considered to be the average of its endpoints."
Given end points of CD
C (-2, -4) and D (6, 2)
The coordinates of the midpoint of CD = ?
Formula to find the midpoint of CD
Midpoint of CD = [tex](\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )[/tex]
C = ([tex]x_{1}[/tex], [tex]x_{2}[/tex]) = (-2, -4) and D = ([tex]y_{1}[/tex], [tex]y_{2}[/tex]) = (6, 2)
Midpoint of CD = [tex](\frac{-2+6}{2}, \frac{-4+2}{2} )[/tex]
= [tex](\frac{-4}{2} , \frac{-2}{2} )[/tex]
= [tex](2, -1)[/tex]
Midpoint of CD = [tex](2, -1)[/tex]
Hence, The coordinates of the midpoint of CD is [tex](2, -1)[/tex].

y = - 2x + 2
2x + y = 2
What is the solution to this ??
Pls helpppp
Answer:
Infintely many solutions
Step-by-step explanation:
I'm going to assume that the capital y is equal to the lowerase y
if you subtract y and two from both sides in the second equation you get
-y=2x-2
you then divide by -1 to get it into a normal form
y= -2x+2
this is the same as the first equation, these lines are the same

The value of Sin 2x if, Sin x = 2 / 5 and tan(x) > 0, is 4 √21 / 25 so, option B is correct.
What is trigonometry?Trigonometry is the branch of mathematics that deals with particular angles' functions and how to use those functions in calculations. There are six popular trigonometric functions for an angle. Sine, cosine, and tangents are their names and acronyms (tan).
Given:
Sinx = 2 / 5 and tan(x) > 0,
Calculate the value of tan x as shown below,
B² = 5² - 2² (Using Pythagoras theorem)
B² = 25 - 4
B = √21
Hence, Tan x = 2 / √21
Calculate the value of Sin 2x as shown below,
Sin2x = 2 Tan x / (1 + tan² x)
Sin2x = 2 × 2 / √21 / (1 + (2 / √21)²)
Sin2x = 4 / √21 / (1 + 4 / 21)
Sin2x = 4 / √ 21 / (25 / 21)
Sin2x = 4 √21 / 25
Thus, the value of Sin2x is 4 √21 / 25.

Identify the zeros of each function. y=(x-7)^2
9514 1404 393
Answer:
x = 7 (multiplicity 2)
Step-by-step explanation:
When the function is written in factored form, the zeros are the values of the variable that make the factors zero.
y = (x -7)(x -7)
The values x = 7 and x = 7 will make the factors zero. The zero is said to be x=7 with multiplicity 2.
__
On the graph, the zeros are the x-intercepts (where y=0). The graph only touches the x-axis, but does not cross. With some experience, you can recognize that this is a zero with even multiplicity (2).
