Cross multiplication
or multiplying by a number which goes in both rates
Answer:
equation form: x=-131/8y -31/40
Step-by-step explanation:
this is addition/elimination
Answer:
b = e + 4
b = e + 4 i think that is the pattern in the table
Similarities: They both are polynomials of degree 2, both of their graphs is a parabola, both have either 2 or 0 real solutions, they are both continuous functions over R
(DOS= difference of two squares, PST=perfect square trinomial
Differences: PST has three terms, whereas the difference of squares has 2. PST's factors are both the same, whereas DOS's elements are conjugates of each other. DOS can always be factored into two distinct polynomials with rational coefficients, whereas PST has two same polynomial factors.
