Answer:
A C(x) =2x³+2x²-18x-11
Step-by-step explanation:
C(x) = W(x) - D(x)
plug W(x) and D(x) into equation
C(x) = 3x³+4x²-18x+4 - (x³+2x²+15)
add like terms now
C(x) =2x³+2x²-18x-11
Answer:
3 and 3/4 cups of cornstarch
Step-by-step explanation:
5/8 cornstarch = 1/6 cup of water
1/6 x 6 = 1 cup of water so we multiply the 5/8 of cornstarch by 6 on the other side, because what you do to one side you must do to the other.
5/8 * 6/1 = 15/4 or 3 and 3/4 cups of cornstarch is needed (this is also 3.75 in decimals)
