Formulas:
A= (b1+b2) /2 X h
A= (22.2+8.52) x 9.86
A=30.72x9.86
A= 302.90
The answer would be x = -9
the variable a would be 4
<span>In order for an equation to have an infinite number of answers, the simplified equation should be x=x. In evaluating the above equation, -3 inserted in the box results in this simplified equation. The answer is therefor #1: -3</span>
One is 1/2 and 2/4 because when you simplify it is 1/2 I think that's the answer but I know that 2/4 in simplify form is 1/2
