Tim was asked to work out the value of 3 12 = 3 + 33.
His working is shown below, but his answer was incorrect.
On which line did he make his first mistake?
3 x 12 : 3 + 33 = 36 = 3 + 33
Line 1
= 36 = 36
Line 2
=
1
Line 3

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
