Why is 12 (m+n) equivalent to 12m + 12n
Answers
Answer 1
Answer:
because 12(m=n) means that you are multiplying 12 times m and 12 times n. So if there is a number outside of parenthesis it gets multiplied by all the nu,beds in the parenthesis.
12(1+2)
36 either way. that is proof. if you want more proof use any number in replace of n and m
12(1+2)
36 either way. that is proof. if you want more proof use any number in replace of n and m
Answer 2
Answer:
Because of the distributive property. You multiply the outside number (12) by the variables inside the parentheses (m and n). Then you add them together, so you get 12m+12n.
You can check it by plugging in numbers for m and n, then solving it both ways. You will get the same answer.

Angle x is 100 degrees because the opposite angle is 80 degrees and they must add up to 180 degrees.
Angle X is 100 degrees because when you are adding up to 180 degrees, subtract the angle you already know from 180 and you will have your answer. 100 degrees

you can divide this picture into 2 pieces, 1 rectangle and 1 triangle.
To find the rectangle, since the opposite sides are equal to each other, the width=6.
the length is 8.
to find the area, use the formula
A = lw
A= 8 x 6
A = 48 units square
that's for rectangle.
for the triangle, use the formula
A = h x b / 2
height=10-6 = 4
base is 8 because the opposite sides are equal in rectangle.
Substitute height and base in the formula.
A= 4 x 8 / 2
A= 32/2
A=16 units square
That's the area of triangle.
Now, you can add the area of rectangle and triangle.
Total area = area of rectangle + area of triangle
A = 48 + 16
A = 64 units square

There are many ways of dividing a triangle, two ways are mentioned below.
Method 1: Dividing a triangle into triangle of three equal areas
After trisecting one side of the triangle connect the two points that trisect the side to the opposite vertex which will make all three triangles have the same length of base and height.
Method 2: Dividing a triangle into two
This method is pretty simple if you are just going straight down the middle to make the two triangles of even base and height.
I hope this helps. If any false information was given I apologize in advance.
