Answer:

Step-by-step explanation:
The first trinomial is

Let the other trinomial be P.
Then

We make P the subject to obtain,

We simplify to obtain,

Hence the other trinomial is 
Question 5 is B
Question 9 is C
Answer:
We are given that 4 lb of candies are bought for $9.00
Therefore, the price of 1 lb of candies is:

Now the amount of candies that can bought for $12.00 is:
lb
Therefore, 5.3333 lb of candies can be bought for $12.00
You have a right triangle situation here, and what you are looking for is the length of the hypotenuse. The leg perpendicular to the ground is 100, and the base angle that is NOT the right angle, is 65. So your equation is set up like this: sin 65 = 100/x. Rearrange that a bit to get x alone: x = 100/ sin 65. Make sure your calculator is in degree mode and solve for x. x = 110.34 feet of string.
