H(a)= a² + 4
g(a)= a + 3
Find (h – g)(a + 2)

-5a-2

Step-by-step explanation:

pulg in the numbers ins h and g

a^2+4−(a+3)(a+2)

Distribute:

=a2+4+−a2+−5a+−6

Combine Like Terms:

=a2+4+−a2+−5a+−6

=(a2+−a2)+(−5a)+(4+−6)

=−5a+−2

=−5a−2

both due 2 rule.

The √42 is a rational number if 42 is a perfect square. It is an irrational number if it is not a perfect square. Since 42 is not a perfect square, it is an irrational number. This means that the answer to "the square root of 42?" will have an infinite number of decimals. The decimals will not terminate nd u cannot make it into an exact fraction.
