If a rectangle is formed by (3y+2) and (y+4), what will be the constant corner?
Answer and explanation
Correct answer: 8
In the rectangle model, the constant corner is obtained by multiplying the constant terms from the two sides. Here, the constant terms are 2 and 4, so the constant corner is \(2\times4=8\). The value 12 comes from multiplying \(3y\) and 4, so it is not a constant term. Exam tip: to find the constant term, multiply only terms that contain no variable.
