Given quadrilaterals ABCD and LMNO, and AC = LN, how can you
show that the corresponding angles of the
quadrilaterals are congruent?

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

simplified version :

3y^2-10y^2x^4+40x^2+3y^2/2x^2

try this. the error is that sariah was combining a constant (4.5) with a variable with a coefficient, thus getting an inaccurate answer.

this is also assuming that you meant to put an equal sign before the 4.5 + x 35 x

to solve this problem, the strategy used is just to solve it yourself and find the correct answer by combining like terms.

hope this !
