Answer:
Step-by-step explanation:
Volume is length times width times height. Because our shape is a cube, by definition, all the sides are the same length, so we are multiplying the number by itself 3 times...we are cubing it. The power then is 3. If we cube 1/3

The area of a rectangle is represented by the expression 2x2 + 10x + 12. Daniel is convinced that the dimensions of this rectangle could be (2x + 4) and (x + 3) or (x + 2) and (2x + 6). Do you agree or disagree with Daniel? Use words to justify your opinion.
Answer:
I agree with daniel
Step-by-step explanation:
Given the area of a rectangle expressed as;
A(x) = 2x²+10x+12
On factorizing;
A(x) = 2x²+6x+4x+12
A(x) = 2x(x+3)+4(x+3)
A(x) = (x+3)(2x+4)
since A(x) = l(x)w(x)
Hence the legnth and width of the rectangle are 2x+4 and x+3.
Also A(x) = 2x²+6x+4x+12 can be factorized as;
A(x) = 2x²+4x+6x+12
A(x) = 2x(x+2) + 6(x+2)
A(x) = 2x+6(x+2)
Therefore I agree with Daniel. The factor differs due to the difference in arrangement of 4x and 6x in the expression. Precedence of values affects the final factors

Given GH with endpoints (-7,3) andH (7. - 11), what are the coordinates of the
mielpoint of GH?
Answer:
Midpoint is (0, -4)
Step-by-step explanation:
x-coordinate of midpoint = (-7 + 7)/2 = 0/2 = 0
y-coordinate of midpoint = (3 - 11)/2 = -8/2 = -4
Midpoint is (0, -4)
Answer:
(0,-4)
Step-by-step explanation:
(x1 + x2/2, y1 + y2/2)
(-7 + 7/2 , 3 + -11/2)
(0/2, -8/2)
(0,-4)

Answer:
y = 5/4 x + 9
y = -5x+4
Step-by-step explanation:
a)The equation of the line in slope intercept form is expressed as y = mx+b
m is the slope
b is the intercept
Given
Slope m = 5/4
y-intercpet = 9
Substitute
y = mx+b
y = 5/4 x + 9
b) Given the coordinates (0,4) and (2, -6)
Slope m = -6-4/2-0
m = -10/2
m = -5
Since the y intercept of the line is (0, 4), hence b = 4
Get the equation
Recall
y = mx+b
y = -5x +4
This gives the required equation
Are 4(a - 3) and 4a - 7 equivalent expressions?
Answer:
Yes
Step-by-step explanation:
Given expression: 3x+9
Take 3 outside from the expression, we get,
= 3(x+3), which is called the equivalent expression
Answer:
No
Step-by-step
We have to multiply the 4 by both the a and the 3 since there a parenthesis around them. This would of course be distributive property. Since you don't know what a is, it would just be 4a and since we can multiply 4 and 3 that would be 12. So, 4(a - 3) is equivalent to 4a - 12.

50 POINTS FOR THIS MATH QUESTION
Answer:
B; 1
Step-by-step explanation:
Firstly, we need to find the inverse of the given function
Let us have f(x) as y
To find the inverse, we set out to make x the formula subject
Thus;
y = √(3x + 6)
square both sides
y^2 = 3x + 6
3x = y^2 - 6
x = (y^2 - 6)/3
To write the inverse, replace y by x
So we have the inverse of the function as ;
(x^2 - 6)/3
So what we have to do here is to substitute 3 for x in the inverse
We have this as;
(3^2 -6)/3
(9-6)/3
= 3/3 = 1
Answer:
1 ( option B )
Step-by-step explanation:
The given equation is ,
[tex]\implies f(x) =\sqrt{ 3x + 6 }[/tex]
Now substituting y = f(x) , we have ,
[tex]\implies y=\sqrt{ 3x + 6 }[/tex]
For finding the inverse , Interchange x and y , we have ,
[tex]\implies x =\sqrt{ 3y + 6 }[/tex]
Now solve for y , we have ,
[tex]\implies x ^2=3y + 6 \\\\\implies 3y = x^2-6 \\\\\implies y =\dfrac{x^2-6}{3} [/tex]
Now replace y with f-¹(x) , we have ,
[tex]\implies f^{-1}(x) =\dfrac{x^2-6}{3} [/tex]
Now put x = 3 , we have ,
[tex]\implies f^{-1}(3) =\dfrac{3^2-6}{3}\\\\\implies f^{-1}(3) = \dfrac{9-6}{3}\\\\\implies \underline{\underline{ f^{-1}(3) = 1 }} [/tex]

Answer:
80 in^3
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base, and h is the height of the pyramid. Here, h=8 in.
__
Here, the base is a triangle. The formula for its area is ...
A = 1/2bh
where b is the base segment of the triangle, and h is the height of the triangle perpendicular to the base segment. Here, b=10 in, and h = 6 in.
The triangular base area is ...
A = 1/2(10 in)(6 in) = 30 in^2 . . . . base area "B"
__
Using the above base area and pyramid height, we find the volume of the pyramid is ...
V = 1/3(30 in^2)(8 in) = 80 in^3
The volume of the pyramid is 80 cubic inches.

The Surface are of a cylinder is 325 inches. The Lateral area is 200 in. What is radius of each base?
Answer:
The radius of each base is 4.46 inches.
Step-by-step explanation:
The surface area (SA) of a cylinder is given by:
[tex]SA = 2\pi rh + 2\pi r^{2} = 325[/tex] (1)
Where:
r: is the radius of each base
h: is the height of the cylinder
Now, the lateral area (LA) is:
[tex]LA = 2\pi rh = 200[/tex] (2)
Hence, by entering equation (2) into equation (1) we have:
[tex] SA = LA + 2\pi r^{2} [/tex]
[tex] 325 = 200 + 2\pi r^{2} [/tex]
[tex] r = \sqrt{\frac{325 - 200}{2\pi}} = 4.46 in [/tex]
Therefore, the radius of each base is 4.46 inches.
