Algebraic equations

1 answer:
Setler [38]3 years ago
4 0

Answer:

x = 80

Step-by-step explanation:

The whole reason algebra exists is to solve for a variable. Therefore, the only way to get x by itself or to see what x equals is to subtract 20 from both sides. Doing this will make x be all alone on one side of the equation and to see what x is.

x + 20 = 100

x + 20 -20 = 100 -20

x = 80

True or false the area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then takin
creativ13 [48]

Answer: The answer is true.

Step-by-step explanation:  The given statement is :

" The area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then taking the sum of their areas".

We are to check its is true or false.

In the attached figure, a regular heptagon ABCDEFG is drawn. Sine the heptagon is regular, so all its sides are equal and all its angles are also equal. So, we can break the heptagon into seven congruent triangles 1, 2, 3, 4, 5, 6 and 7 taking 'O' as the centre of the heptagon.

Finding the areas of these seven triangles and taking the sum will result in the area of the heptagon ABCDEFG.

Thus, the given statement is "TRUE".
