They sold 17 rolls. If 45 were sold at $4 dollars then $4×45= 180 If they made 265 dollars so you have to subtract 180$265-180= 85 dollarsYou know the remainder were sold at $5 dollar and dividing 85÷5= 17
Area of rectangles is l (length) x w (width)
Answer:
P(x) =x³-4x²-31x+70
Step-by-step explanation:
The function is expressed as:
P(x) = (x+5)(x-2)(x-7)
P(x) =(x²-2x+5x-10)(x-7)
P(x) = (x²+3x-10)(x-7)
P(x) = x³-7x²+3x²-21x-10x+70
P(x) =x³-4x²-31x+70
Hence the polynomial is P(x) =x³-4x²-31x+70
