Answer:
52
Step-by-step explanation:
SA=2*4*3+2*4*2+2*3*2=24+16+12=52
Answer: The answer is 52.
Step-by-step explanation: Plug in the formula listed in red words.
2(4x3)+2(4x2)+2(3x2)
= 2(12)+2(8)+2(6)
= 24+16+12
= 52
Therefore, the surface area of the rectangular prism is 52.
Determine the measure of ZA.
45.6°
57.7°
55.2°
32.3°
Step-by-step explanation:
Cos A = 40^2 + 25^2- 34^2 ÷ (2×40×25)
= 200+625-1156 ÷ (2000)
= 1069 ÷2000
Cos A = 0.5345
A= cos inverse 0.5345
A = 57.7

HI I really need help with this its in the picture
Explanation:
The blue rectangle has area of 4a^2*6a^2 = 24a^4

Answer:
distributive propertycombine like termssubtraction (or addition) property of equalityaddition property of equalitydivision property of equalityStep-by-step explanation:
1. The parentheses are gone and the factor outside parentheses has multiplied each term inside parentheses. The distributive property says you can do that.
__
2. 12+2 has been replaced by 14, and 2-20 has been replaced by -18. This is the result when you combine like terms.
__
3. 3x has disappeared from the left side, and the x-term on the right has been reduced by 3x from 5x to 2x. This is the result of subtracting 3x from both sides of the equation. The subtraction property of equality says you can do that. (Note that subtracting 3x is the same as adding -3x.)
__
4. -18 has disappeared from the right side, and the constant on the left has been increased by 18 from 14 to 32. This is the result of adding 18 to both sides of the equation. The addition property of equality says you can do that.
__
5. Both sides of the equation are 1/2 of what they previously were. This is the result of dividing both sides of the equation by 2. The division property of equality says you can do that (provided the divisor is not zero.)
What is the nth term rule of the quadratic sequence below?
8,14,22,32 ,44, 58, 74...
Answer:
y=n^2+3n+4
Step-by-step explanation:
Sequence,S: 8,14,22,32 ,44, 58, 74...
First differences of S: 6,8,10,12,14,16,...
Second differences of S: 2,2,2,2,2,2,....
It is indeed a quadratic since the 1st differences that are the same are the second differences.
So the 1st term is 8. If the 0th term was listes it would be 4 since 8-4=4 and 6-4=2.
This means our quadratic it is in the form
y=an^2+bn+c where c=4.
So we have y=an^2+bn+4.
Now we can find a and b using two points from our sequence to form a system of equations to solve.
(1,8) gives us 8=a(1)^2+b(1)+4
Simplifying gives 8=a+b+4
Subtracting 4 on both sides gives: 4=a+b
(2,14) gives us 14=a(2)^2+b(2)+4
Simplifying gives 14=4a+2b+4
Subtracting 4 on both sides gives 10=4a+2b
So we have the following system to solve:
4=a+b
10=4a+2b
I'm going to solve using elimination/linear combination style.
Dividing second equation by 2 gives the system as:
4=a+b
5=2a+b
Subtract the 2nd equation from the first gives:
-1=-1a
This implies a=1 since -1=-1(1) is true.
If a+b=4 and a=1, then b=3. Because 3+1=4.
So the equation is y=1n^2+3n+4 or y=n^2+3n+4.

A rectangular prism and a pyramid have congruent bases and equal altitudes.Wha is the retio between the volume of the pyramid to the volume of the rectangular prism.What is the answer
Answer:
The required ratio is 1 : 3.
Step-by-step explanation:
Let the length is L, width is W and the height is H.
Volume of the prism is
V = LW H
Volume of the pyramid
V' = 1/3 L W H
Ratio of volume of pyramid to the prism is

You divide by two because it is an inscribed angle, so it will always be half the measure of the arc it is inscribing or enclosing.
What term is used for a bell-shaped curve that is symmetrical regarding the average value of the population (the data being analyzed)?
Answer:
Normal distribution
Step-by-step explanation:
The answer is "normal distribution". This is because in a normal distribution, the mean, median and mode are equal. What this means is that the distribution will be symmetrical with a bell curve unlike in positive or negative skew where it is skewed to either the left or right.

Answer:
maybe you can give them a simple example.
use what they are interested for.
for example if he or she love playing basketball.
you can draw three white ball, if other give you two ball, you can draw two balls. instead, if other want to borrow four balls from you, then you can draw four balls to black and count the left balls.

Answer:
6a = 6 * a
2a * b = 2ab
Step-by-step explanation:
2a * 2b = 4ab not 2ab
6 * a is the same as 6a
5a = 5 * a not 5 + a
3ab has different variables then 3c therefore the expression cannot be true
2ab is the same as 2a * b

Answer:
A.) 10
Step-by-step explanation:
So the relationship here seems to be going by two. Every time the x-value decreases from -2 to +7, the y-value is decreasing by 2. Since you're looking for when x=0, the only number that could possibly do that is when y=10. Before x=1, the y-value can increase by two so it would go from 8 to 10 since we know the relationship for the y-values is 2. Therefore your answer should be A.) 10
