If f(x)=2x+1,then f(-2)=

-3

Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).

To find f(-2) or the value of the function or the value of the function when x = -2, we simply substitute -2 in for x in our function.

So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.

So f(-2) or the value of the function when x = -3 is -3.

c

step-by-step explanation:

at least i think its

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
