8
round each number to the nearest 10, then
640 ÷ 80 = 8 ← estimate
This is a histogram, write out the numbers each time there is an x.
27, 28, 28, 29, 29, 29, 30, 30, 30, 31, 31, 31, 33, 34
for median cross off the sides till you get to the middle
median = 30
P-Q should be -11a^2+4b^2+ab
Answer: the length and width are
(x + 8) and (x + 8)
Step-by-step explanation:
The rug has an area represented by the expression
Area = 4x² + 64x + 256.
The factors in the factored expressions represent the length and width of the rug.
Dividing the the equation by 4, it becomes
x² + 16x + 64 = 0
We would find two numbers such that their sum or difference is 16x and their product is 64x^2.
The two numbers are 8x and 8x. Therefore,
x² + 8x + 8x + 64 = 0
x(x + 8) + 8(x + 8) = 0
The factors are
(x + 8)(x + 8)
