Two lines parallel to the same line

A B = B C, C a = 26, B a C = 84, what are the numbers of a, B and C?

From C a = 26, B a C = 84, B = 42 / 13, from a B = B C, a = C, and because C a = 26, a = C = ± √ 26
Tick is the root sign

(a + b) × C = a × C + B × C is the distributive law of multiplication. What operational law does a × C + B × C = (a + b) × C use

Strictly speaking, this is not an operation law
If we have to talk about it, we can only talk about the law of distribution by multiplication
distributive law
If two numbers multiply by the same number, their product is equal to the sum of two different numbers multiplied by the same number
Letter formula: ab + AC = a × (B + C)
Example: 35 × 37 + 65 × 37 = 37 × (35 + 65) = 37 × 100 = 3700
This is the law of multiplicative distribution
