Answer:
all rectangles are quadrilaterals
Step-by-step explanation:
this is because they have all right angles it doesn't matter the size or measurements, and this goes for squares as well since squares are a type of rectangle and we all know that squares have all equal side lengths and they all have right angles
Answer:2x^2 +10x-5 -9/(x+3)
Step-by-step explanation:
Right off the bat (haha), we can eliminate B as an answer choice because adults are clearly part of the population; in fact, it says in the background information that their entire population is made of adults. A population, in this context, is the group being researched.
D isn't the correct answer; the fact that adults are the target population doesn't validify anything.
C doesn't entirely prove its point because there are other factors that go into the game being biased. In fact, I would say that this study <em>is </em>biased because the board members only attended 1 game when there are 18 teams. Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.
A would be my answer for reasons stated above.
Answer:
{ - 2, 1 }
Step-by-step explanation:
To determine the values let y = 0, that is
(x + 2)(2x - 2) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 2 = 0 ⇒ 2x = 2 ⇒ x = 1
The set of values are { - 2, 1 }
54. -4x^(-5)
55.1/5 x^(-4/5)
