Step 1 :
(23 x 2 - 5) • x 3
Step 2 :
Trying to factor as a Difference of Squares :
Factoring: 8 x 2-5
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Answer:
(8 x 2 - 5) • x 3
Answer:
36 degrees.
Step-by-step explanation:
8+3+4=15
180/15=12
12x3=36 degrees.
Answer:
100
Step-by-step explanation:
they are vertical angles therefore, they have the same measure.
