Find the value of 21 + 4(3^2-5).
a.25
b.37
c.100

Let’s start with PEMDAS. Parenthesis first. 3 squared is 9, then you subtract 5 from 9, which is 4. Then we have to multiply 4 with 4, which is 16. For our last step, we have to add 16 with 21, which is 37. Your answer is B.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
