Two 10 by 10 grids are shown. the first grid has 4 columns and 6 squares shaded green. on the same grid, 6 squares and 4 columns are shaded red. on the same grid, 8 squares are shaded blue. on the second 10 by 10 grid, 3 columns and 8 squares are shaded blue. part a write the multiplication expression shown by the model. do not solve the problem. part b explain the expression written in part a. include the final product and how it is shown with the model.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

ok so what's the question?
