Answer:

Option b. sum of all areas of faces

Step-by-step explanation:

we know that

The surface area of the prism is equal to the area of its bases plus the area of its four rectangular lateral faces

$SA=2B+PH$

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

therefore

sum of all areas of faces

Answer:

The solutions the equation 1 are -1.3 and 2. The solutions to equation 2 are -1 and 0.

Step-by-step explanation:

Isolate the absolute value for equation 1. Then, set two equations equal to 5 and -5.

3x - 1 = 5 and 3x - 1 = -5

Solve for x in both and you would get -1.3 and 2.

Do the same for equation 2.

2x + 1 = -1 and 2x + 1 = 1

Solve for x and you would get -1 and 0.

the area of a rectangular field is x^2-x-72 m^2. The length of the field is x+8 cm. What is the width of the field meters.

Gre4nikov [31]

Hello,

A(x)=x²-x-72 (m²)
L=(x+8) (cm)= (x+8)/100 (m)

We suppose here x≠-8
(in reality x²-x-72>0 ==>x<-8 or x>9
but x+8>0 ==> x>-8
then
only x>9 are solutions)

W=A(x)/ ((x+8)/100 )=100*(x²-x-72)/(x+8)= 100*(x-9)(x+8)/(x+8)=100*(x-9)
