What is the Volume of Rectangular Prism?The volume of a rectangular prism is defined as the space occupied within a rectangular prism. A rectangular prism is a polyhedron that has two pairs of congruent and parallel bases. It has 6 faces (all are rectangular),12 sides, and 8 vertices. As the rectangular prism is a three-dimensional shape (3D shape), the unit that is used to express the volume of the rectangular prism is cm3, m3 and so on.
Given here: The dimensions as 3,3,3
Thus the volume is = 3³
=27
Hence, The answer is 27 units

3. Given the function f(x)=x^2+4x-12:
a. Identify the zeros using factorization.
Answer:
x = -6, 2
Step-by-step explanation:
A zero is the x-value of a point on the x-axis that the graph intersects. Knowing this, we can set the function itself to 0 to find the zeros.
1) Set the function to 0.
[tex]x^2+4x-12 = 0[/tex]
2) Factor out the polynomial. Ask yourself, what are two numbers that have a product of -12 and add up to 4? (In this case, it's 6 and -2.)
[tex]x^2+4x-12 = 0\\(x+6)(x-2) = 0[/tex]
3) Look at the answer from the last step. What do the x's have to equal in order for equation to equal 0? They have to be -6 and 2. Therefore, those are the zeros.
Be sure to show all work and not just the answer. Please help ASAP.

What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
We have to given that;
The expression is,
⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)
Now, We can subtract the expression as;
⇒ (12x² - 11y² - 13x) - (5x² - 14y² - 9x)
⇒ 12x² - 11y² - 13x - 5x² + 14y² + 9x
⇒ 12x² - 5x² - 11y² + 14y² - 13x + 9x
⇒ 7x² + 3y² - 4x
Thus, The value of the difference of the polynomials are,
⇒ 7x² + 3y² - 4x

what is (4x + 7) - (8 - 3x) in standard form?
Math help please right answer
Answer:
135°
Step-by-step explanation:
The sum of interior angles in this rectangle is equal to 720
Two of the angles are right (has 90°)
so 4x + 180 = 720 subtract 180 from both sides
4x = 540 divide both sides by 4
x = 135°
ahhh please help i don’t understand thissss
Answer:
24y^3/x^5
Step-by-step explanation:
Since 6x and 4x are not in a parentheses, they are not being powered by anything. Therefore, those stay on the numerator side.
Anything to the power of something times another to the power of something is always added together. Since -1 + (-4) is -5, x would end up having a power of -5, which would just make it go on the denominator side with just a power of 5.
Same rule with y follows. This would make it 5+ (-2) = 3. Since this is a positive power, it stays at the numerator side.

The distance in miles in the distance in inches vary directly on a map. The legend on the map shows that 16 miles are represented by 0.5 inches. What is the actual distance between the two cities if they are 3 inches apart on the map? In the situation distance in =x.
A) 96 miles
B)72miles
C)80miles
D)104miles
The actual distance between the two cities is 96 miles.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that the map shows that 16 miles are represented by 0.5 inches.
Let x miles would be the actual distance between the two cities
When they are 3 inches apart on the map
According to the given situation, we can write the ratio would be as:
16 miles : 0.5 inches = x miles : 3 inches
⇒ 16/0.5 = x/3
Apply the cross-multiplication operation,
⇒ 0.5x = 48
⇒ x = 48/0.5
⇒ x = 96
Therefore, the actual distance between the two cities is 96 miles.

What is the solution to the equation 6- t = 2t
Answer:
t=2
Step-by-step explanation:
Literally just move all the common like terms onto one side.
6=3t
It is usually prefered to have the variables on the left and the coefficients on the right so you would flip your equation.
3t=6
Then you get t by itself by dividing by 3. Your final answer should be 2.

Step-by-step explanation:
1) Number of white chocolate bars = x
Number of dark chocolate bars = y
Total bars = 15
x + y = 15 --------------(I)
Total cost = Php. 340
20x + 25y = 340 ----------------(II)
2) We can use elimination method to solve this equations.
Multiply equation (I) by (-20) and then add the equations.
(I)* (-20) -20x -20y = - 300
(II) 20x + 25y = 340 {Now add and x will be eliminated}
5y = 40
y = 40/5
y = 8
Substitute y = 8 in equation (I)
x + 8 = 15
x = 15 - 8
x = 7
3) Number of dark chocolate bars = 8
