Answer:
A: second one or middle choice
B: (5x + 8)(3x - 2)
Step-by-step explanation:
First question (A)
It is a trinomial. You can't use the difference of squares on it. The difference of squares have two terms as an answer.
It is not a perfect square. 15 is not a perfect square and c would have to be positive not minus to even think about using a perfect square.
So the A answer is the second one. You need two different binomials to factor this.
Second Question
You could try all the possible pairings and solve them by brute force.
The are five choices the go with the first one (3x + 4). Eventually you would get the answer, you would have to try 5 + 4 + 3 + 2 + 1 = 15 attempts.
There must be a shorter way.
14 means that the expressions are fairly far apart. This was just luck on my part. There is no logic. 8 and 2 for 16 are fairly far apart.
(5x + 8)(3x - 2)
The middle term is 8*3x - 2*5x = 14x and that looks like the answer.
Answer:
Consider
Amount of Rice (cups) : Amount of Water(cups)
1.2/5
2. 3/7.5=2/5
3. 5/12.5=2/5
4. 8/20=2/5
As in all cases Amount of Rice and Amount of water in cups are same.
i.e⇒ Amount of rice × K = Amount of water, where K is constant of proportionality.
So, Among all the statements
⇒ The amount of rice is the dependent value. The amount of water is the dependent value are correct.
Which means if either of them (Amount in cups) is given we can find other.
Slope RS: 2/3
Slope ST: -3/2
Slope TU: 4/6 = 2/3
Slope UR: -1/5
Sides RS and TU have the same slope, so they are parallel.
The slope of side ST is the negative reciprocal of the slopes of sides RS and TU, so side ST is perpendicular to sides RS and TU.
Side UR is not parallel or perpendicular to any other side.
The quadrilateral is a trapezoid.
9/16 = 0.5625
Rounded Equals 0.5630
