<em>Answer</em>
= 11
<em>Explanation</em>
f(x) = x² + 3x- 7
To get the value of f(x) when x = 3, we substitute x with 3 in the function f(x).
f(x) = x² + 3x- 7
= 3² + (3×3) -7
= 9 + 9 - 7
= 11
I’m pretty sure you add 78+55= 133
180-133=47
so 9x+2=47
subtract 2 from 47 and itself
so 9x=45
divide 9 and 45 by 9
so x=5
