9+4
and
7+6
(I believe that is what you can do)
Answer:
x=25, 120
Step-by-step explanation:
The two angles form a straight line so they add to 180
60 + 4x +20 =180
Combine like terms
4x+80 = 180
Subtract 80 from each side
4x+80-80 =180-80
4x= 100
Divide by 4
4x/4 =100/4
x= 25
The exterior angle is
4x+20 = 4*25+20 =100+20 =120
Answer:300
Step-by-step explanation:
Base=20
Height=15
Area of parallelogram=base x height
Area of parallelogram=20 x 15
Area of parallelogram=300
Answer:
See below
Step-by-step explanation:
Colby made a mistake in the 4th line of his work, where he reduced the trinomial 
into 
instead of reducing it to 
. He also did not square root both sides of the equation afterward before he made two seperate equations, leading to incorrect answers.
Continuing on from where Colby made his first mistake, this is how you would correctly solve the rest of the problem:
2 1/6 is the answer. Just subtract 3 2/3 minus 2 1/2<span />
