Are the expressions 8x2 + 3(x2 + y) and 7x2 + 7y + 4x2 - 4y
Equivalent

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
