Please answer the following essay question:
Suppose each dimension of a cube is increased. What happens to the surface area when each dimension is doubled, tripled or, quadrupled?
Answers
Answer:
Step-by-step explanation:
Surface area of a cube = 6a²
When each dimension is doubled, Side =2a
Surface area = 6*(2a)² = 6 * 4*a² = 4*(6a²)
So, when each dimension is doubled, surface area is 4 times of the original surface.
a = 3a
Surface area = 6*(3a)² = 6 * 9 *a² = 9 *6a²
= 9 times the original area
a = 4a
Surface area = 6*(4a)² = 6* 16 * a²
= 16 * (6a²)
= 16 times of original area

Explain how an equation can be written to find m∠CBD.
Answers
Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180

what is m = -8; (-2, 16) in slope intercept form? :)
Answers
Answer:
y = -8x
Step-by-step explanation:
First let's look at what slope-intercept form is.
y = mx + b
m is the slope, which in this case is -8.
b is the y-intercept, which we will find later.
Now that we have identified the parts of the equation, let's plug in what we know. Use the point given for your x and y values.
y = mx + b
16 = -8(-2) + b
Let's simplify this to find b.
[multiply] 16 = 16 + b
[subtract 16] 0 = b
We now have our b-value, which is also our y-intercept. Plug in this value into the standard slope-intercept equation.
y = -8x
This is your equation.
Check this by plugging in the point again.
16 = -8(-2)
[multiply] 16 = 16
This expression is true; therefore, your answer is correct.
Hope this helps!

b) This Indo-Aryan language is a combination with Persian, Arabic, and Turkic elements in its vocabulary, with the grammar of the local dialects. This brought a common language to be spoken in the churches. their language was influential and distinctive. It distinguished them from other races. Aryan is a term that can define a linguistic group, which is a group of people classified as speaking the same language, or can be defined as a race, which is a group of people who comprise of specific and distinct characteristic.
c) The Aryans were the warrior nomadic people that migrated to the Indian subcontinent with their influential culture, religion and language. Aryan culture played a vital role in sculpting Hinduism by influencing the religion with their epics, texts and religious ideologies. The Aryans mixed with the Dravidians to create the complex religion of Hinduism.
d) Prior to the Mauryan Empire (321 to 185 B.C.) there was no organized Aryan government with a class of bureaucrats that acted as administrators. Instead there were numerous ruling chieftains ( rajan ), who were like warlords. They ruled with the support of armies and militias. They were counseled by purohitas , shaman-like figures believed to possess magical powers. When large kingdoms emerged the purohitas served as the equivalent of archbishops and prime ministers for the rulers, performing ritual sacrifices and giving political counsel. Commoners showed respect by kissing the feet of their sovereigns.

Answer:
B

2a+45=180
subtract 45 from both sides which equals 2a=135
divide both sides by 2 which would solve for a.

Find the surface area of the triangular prism.
Answers
Answer:
Triangular prism 1: 132
Triangular prism 2: 828
Step-by-step explanation:
1) triangle+triangle+rectangle+rectangle+rectangle
A of triangle=3*4 divided by 2
12/2= 6
since there are 2 triangles we do 6*2= 12
A of rectangle 1= 10*5= 50
A of rectangle 2= 10*4= 40
A of rectangle 3= 10*3= 30
so SA of whole figure is 12+50+40+30= 132
2) triangle+triangle+rectangle+rectangle+rectangle
A of triangle=9*12 divided by 2
108/2=54
since there are 2 triangles we do 54*2=108
A of rectangle 1= 9*20=180
A of rectangle 2= 15*20=300
A of rectangle 3= 12*20= 240
so SA of whole figure is 108+180+300+240=828

Now, to answer your question, your y-intercept is going to be at point (0,2). Your x-intercepts are going to be at points (-2,0) and (-4,0). Your point is at (-3,-1). And then your lines simply extend from there.

Answer:
-138
Step-by-step explanation:
Distance between midpoint and point (-100) = -100 - (-119)
= 19
Since the [distance between the midpoint and point (-100)] and the [distance between the midpoint and point A] is the same, the distance between the midpoint and point A is also 19. You already know the midpoint is at -119. Since the midpoint is lower than point (-100), point A should be lower than point (-100).
Point A = -119 - 19
Point A = -138
