Answer: 1 = 0

Step-by-step explanation:

The following is a “proof” that one equals zero.

Consider two non-zero numbers x and y such that

x = y.

Then x2 = xy.

Subtract the same thing from both sides:

x2 – y2 = xy – y2.

Dividing by (x-y), obtain

x + y = y.

Since x = y, we see that

2 y = y.

Thus 2 = 1, since we started with y nonzero.

Subtracting 1 from both sides,

Answer:

Yes, one does equal to zero

Step-by-step explanation:

Consider two non-zero numbers x and y such that

x = y. 

Then x2 = xy. 

Subtract the same thing from both sides: 

x^2 – y^2= xy – y^2.

Dividing by (x-y), obtain 

x + y = y. 

Since x = y, we see that 

2 y = y. 

Thus 2 = 1, since we started with y nonzero. 

Subtracting 1 from both sides, 

1 = 0.

Answer:

B. 16 square meters

Step-by-step explanation:

To find the surface area of a square pyramid use this equation: b² + 4(bh/2). b and h will be 2 & 3 respectively.

2² + 4((2 * 3)/2)

First, let's do the work inside the parentheses. We can cancel out the multiplication by 2 and the division by 2, so the right side (by that I mean to the right of the plus sign) just becomes 4(3).

2² + 4(3)

Now, multiply 4 by 3 to get 12.

2² + 12

Next, square 2 to get 4.

4 + 12

Lastly, add 4 and 12 to get 16.

16 m²

After doing the math, I can deduce that the area of this square pyramid is 16 m² (square meters), which is B.

Answer: 130.4

Step-by-step explanation:

find the area of the rectangles

5(8)=40

5(8)=40

4(8)=32

find the area of both of the triangles

formula: 2(bh÷2)

substitute: 2(4 x 4.6 ÷ 2)

solve

2(9.2)

18.4

add all of the areas

40+40+32+18.4=130.4

Answer:

x = 33

Step-by-step explanation:

We have the equation x - 5 = 28 and are asked to solve it.

To solve, we need to find "x", to do that, we need to get x alone.

x - 5 = 28

Add 5 to both sides :

x = 33

Step-by-step explanation:

Answer: x is less then 5 over 4. Open circle on 1.25 shading to the left on the number line.

Step-by-step explanation:

Step 1: 16x is less than 20

step 2: divide by 16, 16x over 16 is less than 20 over 16.

step 3:  x is less than 5 over four (1.25)

Answer: You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole

Answer:

4 13/14 hours.

Step-by-step explanation:

7/9 x h = 3 5/6

h = hours, and I'm going to convert to a common denominator of 18 and an improper fraction on the right to make the next steps easier:

14/18 x h = 23/6

14/18 x h = 69/18

14/18h = 69/18

divide both sides by 14/18. To do that, you multiply by the reciprocal/inverse (which is 18/14)

h = 69/18 x 18/14

h = 69/14

h = 4 13/14

Answer:8 times 4+12+= 44

Step-by-step explanation:

8 times 4 gives you 32 then add 12 to get 44

Answer:

14x+1

Step-by-step explanation:

We add the variables together so it would be 14x. We can't add the 1 so 14x+1.

By the way, can you follow me on Brainly?

Thanks!

What this wants you to do is to write the prefix of the shape, then the meaning of the prefix, then the polygon's name. then I believe the last column is asking for a drawing of the shape, I could be wrong.

Example: Triangle

Prefix: Tri

Meaning: three

Polygon Name: Triangle

Figures:

Answer:

and remember only answer the first there columns.

Step-by-step explanation:

1. you have to find out the prefixes of the polygons, then you have to the meaning of each sides/ give the number of the sides then give the names of the polygons.
