Ireally need this answer i’ve been up for over 12hrs and it’s currently 5: 31 am and i haven’t slept so someone answer this: which expressions can be simplified as 625/n^12? check all that apply. (5n^-3)^4 (5n^-3)^-4 (5n^-4)^3 (25n^-6)^-2 (25n^-6)^2

no it wasn't D it was A and E

Step-by-step explanation: just took the test i broke it down missed one ;(

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.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
