What value is equivalent to (5-3•2^3) + 9-4^2? PLS HURRYYY

-26 is your answer

Step-by-step explanation: 2³ first which = 8 then solve in the parenthesis and all inside parenthesis = -19 so now you have -19+9-4². Now, solve 4² which = 16 so now you have -19+9-16 then solve that and it should give you -26.

Hope this helped you

there you go :-  

cos a = square root of (1- square of sin a)  

tan = sin a / cos a = sin a/(square root of (1- square of sin a))  

cosec a = 1/sin a  

sec a = 1/cos a = 1/(square root of (1- square of sin a))  

cot a = cos a /sin a = (square root of (1- square of sin a))/sin a
