Plz answer asap need to finish my assignments thank you so much

24, 16

Step-by-step explanation:

Perimeter of rectangle ABCD

= 2 * ( Length + Width)

= 2 * (10+2)

= 2 * 12

= 24

Perimeter of rectangle EFGH

= 2 * ( Length + Width )

= 2 * ( 4 + 4 )

= 2 * 8

= 16

i would have to say it is c.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
