Agarden has width √ 13 and length 7 13 − − √ 713 what is the perimeter of the garden in simplest radical form?

16√13

Step-by-step explanation:

width (w) = √13

length (L) = 7√13

Perimeter (P) = 2L + 2w

P = 2(7√13) + 2(√13)

   = 14√13 + 2√13

   = (14 + 2)√13

   = 16√13

step-by-step explanation:

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.
