b) 2w (squared) -19w
d) 3w-19
The expression that represents the area of the classroom floor is 2w -19w
'A plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.'
According to the given sum,
Width = w
Length = 2w - 19
Area of a rectangle = length × width
= w × (2w - 19)
= 2w ( squared ) - 19w
Hence, we can conclude that the expression that represents the area of the classroom floor is 2w (squared) - 19w.

Answer:
B
Step-by-step explanation:
The area is calculated by length×width. In this case you don't know the length or width precisely so you say 2w (squared) because it's the width×width and you subtract 19 because then you actually have width×length.
Answer:
95
Step-by-step explanation:
To round 95.131 to the nearest whole number consider the tenths’ value of 95.131, which is 1 and less than 5. Therefore, we have to round down: the whole number ones place value of 95.131, 95, remains 95, and the decimal point and all digits (.131) are removed.
95.131 rounded to the nearest whole number = 95
Answer:
95.13 !
Explanation:
Its 131 so its 1 away from 130, which is the closest hundredth. Also, we don't really need the 0, so its 95.13, instead of 95.130!

Answer:
The answer is D 400 ÷ 10
Step-by-step explanation:
x= 19
x can not be determined from the information given
x = 27.25
Answer:
x=35
Step-by-step explanation:
These are alternate interior angles. Since a and b are parallel, they are equal
5x - 54 = 3x+16
Subtract 3x from each side
5x-3x -54 = 3x -3x +16
2x -54 = 16
Add 54 to each side
2x-54+54 = 16+54
2x = 70
Divide each side by 2
2x/2 = 70/2
x = 35
