Answer: √5
2.7 is a rational number because it's a terminating decimal which means that the decimal does end and all terminating decimals are rational numbers.
-3 is a rational number because it's an
integer and all integers are rational.
√4 is rational because it's a perfect square which means that a number can be multiplied by itself to get 4 and that number is 2.
√5 is no rational! It's impossible to find a whole number multiplied by itself to give us 5 which means that it's
non-terminating and non-repeating.
Answer:
The answer is 45°
Step-by-step explanation:
An easy way to remember how to solve you would first add both known angle measurements and subtract 180° from that and then make sure you give it absolute value so the answer is positive instead of negative.
Answer:
(p - 3)(q + 1)
Step-by-step explanation:
Rearrange the terms in the expression as
pq - 3q + p - 3 ( factor the first/second and third/fourth terms )
= q(p - 3) + 1(p - 3) ← factor out (p - 3) from each term
= (p - 3)(q + 1) ← in factored form
Answer:
I think that Nick is correct because you are going to have to make your answer positive and when you do the two fractions -4/9 + -6/9 are going to be 6/9 + 4/9 and there is already a addition sign in the last problem we are just going to keep it there. And when we add we get 10/9 or 1 1/9
If i get it wrong please don't hate im just in 7 grade ok :(
