a rectangular piece of metal is 10 in longer than it is wide. squares with sides 2 in long are cut from the four corners and the flaps are folded upward to form an open box. if the volume of the box is 671 in, what were the original dimensions of the piece of metal?
Answers
The length and width of the piece of metal are 28 and 18 inches respectively.
What is volume?
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
Dimension of the rectangle;
Width(w)
Length,L= 10 + w
volume of the box = length * width * height
Dimension of the box;
length of box, (x + 10) - 4 = x + 6
width of box,(x - 4)
height of box = 2
The volume of the box is 672 in³;
⇒V=lwh
⇒V=2 (x -4)( x + 6)
⇒672 in³ = 2x² + 4x - 48
⇒2x² + 4x - 720 = 0
⇒x^2 + 2x - 360 = 0
⇒(x +20)(x - 18) = 0
⇒x = 18
⇒x=-20 (value of the dimension will not be negative.
The width of an original piece of metal is;
Width,w=18 inches
length,l= 28 inches
Hence. the length and width of the piece of metal are 28 and 18 inches respectively.

What is algebraic expression?An algebraic expression is one that has been constructed using integer constants, variables, and algebraic operations. A good example of an algebraic expression is 3x 2 2xy + c.
Given Data
Suppose the number is v
1) To obtain: four times the product of v and 3.
Accordingly, we must first add v and 3, and then multiply the result by 4.
The mathematical expression is as follows.
= 4(v+3)
2) Assume that v is the given integer.
What we're aiming for is: 7 less than 15 times v.
This calls for multiplying the v by 15 and then taking 7 out of the result.
The expression in algebra would be as follows:

The area of the triangle for the given parameter is 12.4 squared cm.
How to calculate the area of the triangle?
In mathematics, the area of the triangle is classified into three forms isosceles, scalene and equilateral. Depending upon the sides of the triangle, it is classified. That means, when the two sides are equal then the triangle is isosceles triangle.
According to the question, the given parameters for the calculation of the area of the triangle is as written below:
Side of the triangle(a) = 5.2 cm. Angle of a triangle(B) = 67°.
Using standard formula for the area of the triangle, we get:
Area of the triangle = (1/2)(5.2)(5.2)sin(67°) = 12.4384 = 12.4 squared cm.
Hence, the area of the triangle for the given parameter is 12.4 squared cm.

f(x) = 3 x + 1 and g (x) = 2x - 3. find g (f(x))
Answers
Answer:
6x -- 1
Step-by-step explanation:
To Solve for g(f(x)), bear in mind
f(x) = 3x + 1
g(x) = 2x -- 3
g(f(x)) = 2x -- 3. (Calm down right?)
Let x = f(x).
if you recheck g(x) = 2x -- 3 so we got the (x) from it (do you get?)
g(f(x)) = 2(3x + 1) -- 3
g(f(x)) = 6x + 2 -- 3
g(f(x)) = 6x -- 1
#AllonGod
Answer:
Step-by-step explanation:
To find g(f(x)), first, understand that this means we are going to use the function of f(x) where the x would be in g(x).
1. First, identify the x in g(x) and replace it with the function of f(x)
g(x)=2x-3; so g(f(x))= 2(3x+1) -3
2. Simplify the equation by distributing the 2 and combining like terms.
2*3x=6x and 2*1=2, so we are left with 6x+2-3. After, just do 2-3 to end up with
g(f(x))=6x-1
Area of a triangle with a vertical height of 1/2 m and base of 1/4 m.
Answers
Answer:
1/16 squared meters
Step-by-step explanation:
The formula to find the area of a triangle is [tex]\frac{Base * Height}{2}[/tex]
We can form an equation if we substitute the values (base and height).
[tex]\frac{1/2*1/4}{2}[/tex]
1/2 * 1/4 = 1/8
and [tex]\frac{1/8}{2}[/tex] = 1/16
Therefore, the area of a triangle with a vertical height of 1/2 m and a base of 1/4 m is 1/16 meters squared.

Answers
The vertex and the axis of symmetry are (-2, -6) and x = -2, respectively
How to determine the vertex and the axis of symmetry?The equation of the function is given as
f(x) = x^2 + 4x - 2
The above equation is a quadratic equation
Next, we plot the equation on a graph (see attachment)
The vertex of the graph is the minimum or the maximum of the graph
In this case, we have
Minimum= (-2, -6)
This means that
Vertex = (-2, -6)
The axis of symmetry is the x-coordinates of the vertex
So, we have
x = -2
Hence, the vertex is (-2, -6) and the axis of symmetry is x = -2

By using internal angles of the triangles and the definition of supplementary angles, the measure of the angle MNP is equal to 54°.
How to determine a missing angle in a geometric systemHerein we find a geometric system formed by two common semirrays with a common vertex at point N and a line segment MP such that triangle MPN is a right triangle. By Euclidean geometry we know that the sum of the measures in the internal angles equals 180°:
m ∠ NMP + m ∠ MNP + m ∠ MPN = 180° (1)
And the two angles at point P are supplementary angles:
24 · x + m ∠ MPN = 180° (2)
Then, by (1):
90° + 9 · x + m ∠ MPN = 180°
m ∠ MPN = 90° - 9 · x
By (1) in (2):
24 · x + 90° - 9 · x = 180°
15 · x = 90°
x = 6
