Multiply the expressions below using a generic rectangle. Then verify Casey's pattern (that the product of one diagonal equals the product of the other
diagonal).

A. (4x-1)(3x+5) B. (2x-7y)^2

125 yards

step-by-step explanation:

i take 75 plus 50.

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
