£675

Step-by-step explanation:

1bean bag =£45

10 bean bags =£45×10=£450

10%of450=10/100×450=45

discounted price =450-45=405

coffee machine=£320

total cost =£320+£405=£725

left over=£1,400-£725=£675

sorry not sure

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.
