Francesca tried to evaluate an expression. Here is her work: 3(5)2–18÷3

=

3(25)–18÷3 Step 1

=

75–18÷3 Step 2

=

57÷3 Step 3

=

19 Step 4

Is Francesca's work correct?

Who can me with this algebra for your guys.

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 3x^2 -2x =0 2) 2x^2 =3x 3) 2 * 2 = 2 * 2 4) 6 +2x = 2(4x)
