Subtract 2 from one number and that answer add 3, subtract 2, and add 3 again. continue doing that.all through.
D because y (time spent) = 50 × x (distance travelled)
225÷4.5=50
x÷y=50
Which expression is equivalent to 100 n2 − 1? (10n)2 − (1)2 (10n2)2 − (1)2 (50n)2 − (1)2 (50n2)2 − (1)2
Regroup:
100n^2-1
=10^2n^2-1
=(10n)^2-1^2
So the correct answer is :
(10n)^2-1^2
To attempt to factor a polynomial of four or more terms with no common factor, first rewrite it in groups. Each group may possibly be separately factored, and the resulting expression may possibly lend itself to further factorization if a greatest common factor<span> or special form is created.</span>
Answer:
the answer is a hope this helps you 4/5 because a proportional relationship. two quantities and it represented by a graph
