I assume the first term of the trinomial is 2x^2, and you left out the exponent.
Multiply each term of the binomial by each term of the trinomial.
Then collect like terms.
Answer:97/12 + (-4 1/3) = 15/4
Step-by-step explanation:
15/4 - (-4 1/3) = 97/12
97/12 + (-4 1/3) = 15/4
Answer:
81
Step-by-step explanation:
When two variables have direct variation, as one variable increases the other variable increases or as one variable decrease, the other decrease. While for an inverse variation, as one variable increase, the other variable decrease or as one variable decrease, the other variable increase.
Given that a ∝ 1/b. Also b ∝ c².
Hence if k is the constant of proportionality, we have:
a ∝ 1 / c²
a = k / c²
When a = 1, c = 3, hence:
1 = k / 3²
k = 1 * 3²
k = 9
Therefore:
a = 9 / c²
When c = 1/3
a = 9 / (1/3)²
a = 9 / (1² / 3²)
a = 9 / (1 / 9)
a = 9 * 9
a = 81
I believe it is distributive property
