Whenever two lines intersect, they form two pairs of vertical angles. Vertical angels have a common vertex, but they are never adjacent angles. Fin, vertical angles are always congruent.
Answer:

Step-by-step explanation:
When we multiply a polynomial by a specific monomial, all terms in the polynomial get multiplied by the monomial.
So we can do this by term.

Multiplying x by x to the something power will just increase the exponent on the x term by one (since powers are just x multiplied by itself). This means the exponent here will increase by 1, so this becomes
.
Same logic applies to the second term:
, raise the exponent by one,
.
For the third term, if there is no exponent on a term you can assume it's exponent is 1 (so
in this case - as
). Again, using the same logic, this turns into
.
For the last term, when we multiply a constant by a variable, we get a term with a variable and a coefficient - the constant becomes the coefficient and the variable stays the variable. Therefore,
.
Adding these terms all together gets us
.

1. A= a²
2. Find the square root of the area to find the length of its side length.
3. √81= 9
√89= 9.43
4. For the first square, the side length is a rational number because 9 is a whole number. For the second square, the side length is irrational because the decimals do not repeat themselves.
Answer:
Exponential growth
Step-by-step explanation:
This is not a negative so it is growing.
