Step-by-step explanation:
angles 2 (and 3) are supplementary angles of the given angle, this means that the given angle and either one of the two angles i just mentioned should add up to 180
angle 4 is vertical to the given, so this means that they are congruent
angle 8 corresponds to 4 and 5 corresponds to the given, so they are all congruent
angles 7 and 6 correspond to 3 and 2, so they are also 40

3. Given the function f(x)=x^2+4x-12:
a. Identify the zeros using factorization.
Answers
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.

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

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
Answers
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.

Step-by-step explanation:
Literally just move all the common like terms onto one side.

3t=6
Then you get t by itself by dividing by 3. Your final answer should be 2.
In your own words, explain how the formula for the area of a square is related to the formula for the volume of a cube
Answers
Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches.

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.
