Cranberry juice costs $6.30 per quart and apple juice costs $3.60 per quart. Terrence wants to know how many quarts q of cranber

Korvikt [17]

We know that:

Cost (Cranberry Juice): 6.3 per quart

Cost (Apple Juice): 3.6 per quart

Quantity (Apple Juice): 4 quarts

Quantity (Cranberry Juice): q quarts

Further we know that Terrence wants the cost of the juice to be 4.5 per quart

Hence Total Cost = Cost per quart × Total Number of quarts = (Cost per quart for Apple Juice × Total Number of Apple Juice Quarts) + (Cost per quart for Cranberry Juice × Total Number of Cranberry Juice Quarts)

⇒ Total Cost = 4.5 × (q+4) = 6.3 × q + 3.6 × 4

⇒ 4.5(q+4) = 6.3q + 14.4, which matches with option D

Hence, the correct option is D

F left parenthesis x right parenthesis equals 9 x cubed plus 2 x squared minus 5 x plus 4 and g left parenthesis x right parenth

Jet001 [13]

The answer is 2x(2x²+x+1).

When we subtract polynomials we combine like terms:
(9x³+2x²-5x+4)-(5x³-7x+4)

9x³-5x³=4x³
2x²- 0 = 2x²
-5x--7x=-5x+7x=2x
4-4=0

This gives us
4x³+2x²+2x

Each of these is divisible by 2, and each has an x, so we factor those out:
2x( )

4x³/2x = 2x²:
2x(2x² )

2x²/2x=x:
2x(2x²+x )

2x/2x = 1:
2x(2x²+x+1)
