The correct answer is c.
because he ordered 45 pounds of oranges
twice as many pounds of apples as oranges so:45*2=90 pounds of apples
and 20 pounds more strawberries than apples so: 90+20=110 pounds strawberries
in total:45+90+110=245 pounds of fruits!!
The first three items are of equal value :)
500/5 + 10/5 + 2/5 = 100 + 2 + 2/5 is about 102, or exactly 102.4.
This does not have a cube root. It has a CUBIC (degree 3) term.
In Algebra II we learn about rational roots theorem, synthetic division, and Descartes' rule of signs.
It happens that 2 is a root, so x-2 is a factor.
When we divide this synthetically, we obtain the depressed polynomial (other) factor as x2+3x +6.
