Answer:
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
4y - 20.......u need to find a common factor that can go into 4y and 20.....the only common factor is 4. So u can factor that out.....4 goes into 4 one time (but do not forget the y) and 4 goes into 20 five times....4(y - 5)
4(y - 5)...u can also check ur answer by distributing the 4 through the parenthesis and getting 4 * y - 4 * 5 = 4y - 20
Answer: 10%
Step-by-step explanation:
The difference between his estimated and actual distance is 15 - 13.5 = 1.5
The percentage of error is the difference divided by the actual value.
1.5÷15 = 0.10
Converted to a percentage, it is 10%
Answer:
If use the area of the frame the area of the photo will be included
Area of frame = (22 + 2 x) * (20 + 2 x) = A
440 + 2 x ( 20 + 22) + 4 x^2 = A
A = 4 x^2 + 84 X + 440
An expression which combines variables, numbers and at least one operation is called binomial. Binomial consists of two terms that is separated with at least one operation. Operations may include addition, subtraction, multiplication and division.
