Answer:
2x^2 - 2
Step-by-step explanation:
FOIL:
First outer inner last.
So we take (x-1) and (2x+2) and multiply the two first terms together.
2x^2
Next, we do the two outer terms.
2x^2 + 2x
Inner is next.
2x^2 + 2x - 2x
Then the last two terms in the equation.
2x^2 + 2x - 2x - 2
Then simplify:
2x^2 - 2
Answer:
26
Step-by-step explanation:
I can be wrong but i most likely sure it is correct because a triangle is 180 degrees you have to add 102 with 52 take that total and subtract it with 180 to find that angle is what you need to find the length. Again i am not sure but might be right.
Answer:

Answer:
Step-by-step explanation:
area of semi circle=πr^2/2
=3.14*(2.4)^2/2
=3.14*5.76/2
=18.0864/2
=9.0432 cm^2
If degree of variable is one then eq. is linear
so given is linear.
