Question

Solve the exercise below given that: $X=4$

$(X+4)(3+X)$

00:00 Solve

00:04 Let's substitute X = 4 according to the given data and solve

00:18 Calculate each parenthesis separately

00:20 There is multiplication between parentheses

00:25 And this is the solution to the question

We start by substituting the value of $X$

$(4+4)(3+4)$

First, we perform the calculation in parentheses

$(8)(7)$

After this, we solve the parentheses and can continue with the simple multiplication exercise.

$7\times 8=56$
