Answer:
Step-by-step explanation:
The angles are complimentary, so they add to 90
6x + 3 + 7x + 9 = 90 Combine like terms
13x + 12 = 90 Subtract 12 from both sides
13x = 90 - 12 Combine
13x = 78 Divide both sides by 13
x = 6
<A = 6x + 3
<A = 6*6 + 3
<A = 36 + 3
<A = 39

<h3>Given:</h3>
▪ 
First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:

Divide the coefficient:

Divide the base by subtracting the exponents of the base 10.

Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.



Answer:
-8 < x, the answer is B
Step-by-step explanation:
Since its starting from -8 and your going to the greater side of the numberline teh variable will be greater than -8, whenever the circle is filled it just means greater than or equal to depending on which side its going. If its filled in, it means that its greater than or equal to or less than or equal to depending on which side its going towards.
Reminder:
<--------------- Negative side/Lower -----------------------> Positive side/Greater
