<span> Not 100% sure but I think it is: consumers need to be better informed about what services are available and what those services cost.</span>
The answer is 45 since every triangle is equal to 180 and angle 7 is 90 ,and the other two are equal you subtract 90 from 180 and divide the rest by two
Area = 5 x 5 = 25in
perimeter = 4(5) = 20 inch
V = x³ - 6x²y + 12xy² - 8y³
V = (x - 2y)³
= (x - 2y)(x - 2y)(x - 2y) ( expand first pair of factors )
= (x² - 4xy + 4y²)(x - 2y) ( multiply terms in first by terms in second )
= x³ - 4x²y + 4xy² - 2x²y + 8xy² - 8y³ ( collect like terms )
= x³ - 6x²y + 12xy² - 8y³
