Find the area of the rhombus. Leave your answer in simplest radical form. 60°
9

A) 18/3
B) 8176
C) 16273
D) 150/3​

162√3.

Step-by-step explanation:

Area = 1/2 * p * q  where p and q are the diagonals.

Here p = 2*9 = 18 and we need to find q.

tan 60 = 0.5q/9

0.5q = 9 tan 60 = 9*√3

q = 18√3

So the area of this rhombus

= 1/2 * 18*18√3

= 162√3

=

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
