An expression that is equivalent to 2.3 x 2.3 x 2.3 x 2.3 x 2.3 is 2.3^
Answer:
∠BAC = 105°
Step-by-step explanation:
2(5x) = 9x+21
10x = 9x+21
reduce:
x = 21
∠BAC = 5x = 105°
Note that both sides were multiplied by 5.
So that would be "Multiplication Property of Equality."
Basically, this property states that if a=b, then ac = bc.
we know that
The Zero Product Property states that if
, then either
or
(or both)
we have

rewrite the expression

so



therefore
<u>the answer is the option</u>
x = –3 or x = 2
