We can solve equations like this using the FOIL (First Outside Inside Last) method.
(2x)(x)+(2x)(3)+(1)(x)+(1)(3) -> 2x^2+6x+x+3

Step-by-step explanation:
since the volume formula is given in the picture,
volume of the cylinder = π x 3.75^2 x 6.21 = 274.349....in^3 (this is the exact answer)
HOWEVER,
since question says round off to nearest whole number,
Volume = 3 x 4^2 x 6 = 288in^3
therefore, answer = option C.
Hope that helps.

I checked in the RSM system thing
The image point of A after a translation right 1 unit and down 2 units is the point B (9,3). Determine the coordinates of the pre-image point A.
Alright, it went 1 to the right and down 2 times.
So for point B, you calculate the opposite.
Point B goes 1 left while going up by 2.
(9 - 1, 3 + 2) = (8, 5)
Pre-image point A is (8, 5)
The preimage of point A before a translation right 1 unit and down 2 units
is (8, 5).
What are transformations?Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.
Dilation: The preimage is scaled up or down to create the image.
Reflection: The picture is a preimage that has been reversed.
Rotation: Around a given point, the preimage is rotated to create the final image.
Translation: The image is translated and moved a fixed amount from the preimage.
Given, The image point of A after a translation right 1 unit and down 2 units is point B (9, 3) so we go exact opposite 1 unit left and 2 units up which is
(- 1, 2).
∴ The pre-image point A is (8, 5).

A milk truck delivers 396 dozen gallons of milk to stores in 1 day. Write and solve an equation to find n, the number of gallons of milk the milk truck delivers in 1 day. nothing
Answer:
[tex]n = 4752 \ gallons[/tex]
Step-by-step explanation:
Given
Delivery: 396 dozens gallons in a day
Required
Determine the number of gallons in a day
From the question above, we understand that:
[tex]n = 396\ dozens\ gallon[/tex]
From unit conversion:
[tex]1\ dozen = 12[/tex]
So:
[tex]n = 396\ dozens\ gallon[/tex] becomes
[tex]n = 396 * 12 \ gallon[/tex]
[tex]n = 4752 \ gallons[/tex]
Hence, 4752 gallons of milk is delivered daily

Classify the system and identify the number of solutions.
4x + 3y + 6z = 25
x + 5y + 7z = 13
2x + 9y + z = 1
Answer:
consistent, independent; one
Step-by-step explanation:
The solution is (4, −1, 2). Because the system has one solution, it is consistent and independent.
The system of equation is consistent and have unique solution.
What is Matrix?Rows and columns of numbers are arranged in a matrix.
A rectangular matrix is a grouping of numbers into rows and columns. The matrix A, for instance, has two rows and three columns.
Given:
4x + 3y + 6z = 25
x + 5y + 7z = 13
2x + 9y + z = 1
Writing the into matrix form
A= [tex]\left[\begin{array}{ccc}4&3&6\\1&5&7\\2&9&1\end{array}\right][/tex] and B= [tex]\left[\begin{array}{ccc}25\\13\\1\end{array}\right][/tex]
Now, find the determinant we get
[tex]D_x[/tex] = -796, [tex]D_y[/tex]= 199, [tex]D_z[/tex] = -398
and Determinant of matrix A= -199
So, x= -796/-199= 4
y= 199/-199 =-1
z= -398/-199 = 2
hence, the system of equation is consistent and have unique solution.

in the circle shown, AB is tangent to circle o at point and OC is a radius
Which relationship is true?
Answer:
A. [tex] \overline{OC} \perp \overline{AB} [/tex]
Step-by-step explanation:
According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.
Given that [tex] \overline{AB} [/tex] is a tangent of the circle O, at a point C, and [tex] \overline{OC} [/tex] is a radius, therefore, it follows that:
[tex] \overline{OC} \perp \overline{AB} [/tex].
This means the radius of the circle is perpendicular to the tangent formed at point C.

Which is different? Find "both" answers.
Find AC+CB.
Find BC−AC.
Find AB.
Find CA+BC.
Question 2
The "different" answer is
. The "same" answer is
.
Answer:
Step-by-step explanation:
Question 1
BC - AC and AB will provide different answers when compared to AC + CB and CA + BC. This is because AC means A multiplied by C (AC) or C multiplied by A (CA); thus means AC and CA are the same. Also, CB means C multiplied by B (CB) or B multiplied by C (BC); thus means CB and BC are the same.
Hence, Finding AC + CB will provide the same answer as finding CA + BC
However, finding BC - AC will provide different answer to finding AB because BC - AC means the multiplication of A and C is subtracted from the multiplication of B and C - the answer thereof will most likely be different from the multiplication of just A and B.
Question 2
From the explanation above,
The "different" answer is
Find BC - AC and Find AB
The "same" answer is
Find AC + CB and Find CA + BC
