Step-by-step explanation:
3(p2q + pq2 - pq) - 6pq + 3pq2 =
3[-20 × 2 + (-20) × 2 - (-20)] - 6 × (-20) + 3 × 2 × (-20) =
3[-40 + (-40) + 20] - 6 × (-20) + 3 × 2 × (-20) =
3(-40 - 40 + 20) - 6 × (-20) + 3 × 2 × (-20) =
3(-80 + 20) - 6 × (-20) + 3 × 2 × (-20) =
3 × (-60) - 6 × (-20) + 3 × 2 × (-20) =
-180 + 120 + 6 × (-20) =
-180 + 120 + (-120) =
-180 + 120 - 120 =
-60 - 120 = -180
Answer:
9 cans
Step-by-step explanation:
We find the area of the wooden court
The area of a rectangle is given as:
Length × Breadth
The dimensions of the court are given as:
Its length is 43 feet and its width is 36 feet.
The area of this rectangle(wooden court) is:
43 feet × 36 feet
= 1548 square feet
From the question:
Suppose each can of wood stain covers 172 square feet.
172 square feet = 1 can
1548 square feet = x cans
Cross Multiply
172x = 1548
x = 1548/172
x = 9 cans
She would need 9 cans to cover the entire court
Answer:
Sample is biased
Step-by-step explanation:
In her experiment, Gloria assumes that the reading habits of the students in her school district are exactly the same to that of students in all state schools. This assumption is unlikely to be true and, therefore, this statistic is misleading because the sample used is biased.
From her data, all Gloria can do is report the percentage of students that read more than one book per month in her school district.
