The binomial factors of the quadratic trinomial may take the forms of (y + a) and (y + b). The sum of a and b is equal to the numerical coefficient of the second term and their product should be equal to the constant. If a is equal to -2, b is equal to -8. Thus, the second factor is (y - 8).
7x + 5(x + 3) + 4x + x + 2 =
= 7x + 5x + 15 + 4x + x + 2 = 17x + 17
Answer:
k=13t/t+6
Step-by-step explanation:
kt=13t−2k(3)
Step 1: Add 6k to both sides.
kt+6k=−6k+13t+6k
kt+6k=13t
Step 2: Factor out variable k.
k(t+6)=13t
Step 3: Divide both sides by t+6.
k(t+6)t+6=13tt+6
k=13t/t+6
