A reflection of shape l across the yaxis, followed by a
, and then a translation left 6 units and down 4 units confirms congruence
between shape and shape II.
Alternatively, a
of shape Il about the origin, followed by a reflection across the yaxis, and then a translation right 4 units and up 6
units confirms congruence between shape Il and shape I.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
