What value of A would make the expression A (x+3) equivalent to 7x+21
To make the expression A(x+3) equivalent to 7x+21, we need to find the value of A.
We can distribute A to both terms inside the parentheses to get:
Ax + 3A = 7x + 21
Now, we can compare the coefficients of x on both sides:
A = 7
Therefore, the value of A that would make the expression A(x+3) equivalent to 7x+21 is A = 7.
