Hi Christian,

I got an error on this:

"There was an error in this part's marking algorithm. Please report this. There is a variable namedmarks, which is also the name of a marking parameter. Please rename the variable."

Best,

Tom

Indeed it should! I've changed the pattern restriction to fix that.

I believe pattern should be (+-$n? *$v + +-$n)^2 + +-$n

Set accuracy to 0 so the exact value must be given, i.e. in terms of $\pi$ instead of a single decimal.

Fixed the measurements in drawingA

Saved a checkpoint:

Fixed the pattern restriction so a negative quadratic term with no coefficient is OK.

#### Christian Lawson-Perfect on Linear Equations2 years, 11 months ago

Saved a checkpoint:

Thanks! I've fixed both of those.

#### Tom Goodale commented on Linear Equations2 years, 11 months ago

There are a couple of typos in the pairs variable:

• In the first equation c should equal -5.5
• The third equation should have "-2" on the right hand side instead of "+2"
