2/3p - 1/4p

Plug 2.4 for p

2/3(2.4) - (1/4)(2.4)

1.6 - 0.6

= 1.0

F(x) = 3x3 – 2x2 + x - 4 at x = -3

Yuri [45]

Steps to solve:

f(x) = 3x³ – 2x² + x; x = -3

~Substitute

f(-3) = 3(-3)³ - 2(-3)² + (-3)

~Solve the exponents

f(-3) = 3(-27) - 2(9) + (-3)

~Multiply

f(-3) = -81 - 18 - 3

~Subtract

f(-3) = -102

Best of Luck!

Answer:

104 units

Step-by-step explanation:

One key thing to note about a reflection is that side lengths and angle measures will always remain the same on the reflected figure. With that in mind, let's note the side lengths in both the original and reflected figures.

$AB=\\BC=20\\CD=30\\AD=$

$A'B'=22\\B'C'=\\C'D'=\\A'D'=32$

Remember, since side lengths are the same, let's fill in the missing values with the values of the side lengths given in each of the figures:

$AB=22\\BC=20\\CD=30\\AD=32$

$A'B'=22\\B'C'=20\\C'D'=30\\A'D'=32$

See? Notice how the values are the same! To find the perimeter ( $P$ ) of a quadrilateral, we have to add each side length:

$P=22+20+30+32$

Solve:

$P=104$
