Plug the -4 into equation
f(-4) = 5(-4) -3
multiply 5•-4= -20
then subtract -20-3
when you have two negatives you add
= -23
The first step would be to isolate the square root on the left side. √x-6+2 = 6 √x-6 = -2+6 √x-6 = 4We would have to take away the radical on the left and square the equation. (√x-6)2 = (4)2 x-6 = 16Finally, x -22 = 0 x = 22
Step-by-step explanation:
Equation: 3.9^2 + x^2 = 11^2
x = 10.29
Answer:
DON'T LOOK AT THE PICTURE!!
Step-by-step explanation:
Answer:
1350
units²
Step-by-step explanation:
The regular hexagon consists of 6 equiangular triangles
The area (A) of a equilateral triangle is calculated as
A =
( s is the side length )
Here s = 30 , then
A =
=
= 225
units²
Thus the area of the regular hexagon is
area = 6 × 225
= 1350
units² ← exact value
≈ 2338.3 units² ( to 1 dec. place )
