Find ​(a) PQ to the nearest tenth and ​(b) the coordinates of the midpoint of __ pq.

Answers

Answer:

a) 5units

b) (4.5, 4)

Step-by-step explanation:

Let the coordinate of P and Q be P(3, 2) and Q(6, 6)

PQ can be gotten using the distance formula;

PQ =√(6-2)²+(6-3)²

PQ = √4²+3²

PQ =√16+9

PQ =√25

PQ = 5units

Midpoint M is  expressed as;

M(X, Y) = {(x1+x2)/2, y1+y2/2}

X = x1+x2/2

X = 3+6/2

X= 9/2

X = 4.5

Similarly;

Y = y1+y2/2

Y = 2+6/2

Y = 8/2

Y = 4

Hence the midpoint of PQ is (4.5, 4)

Is (x+4)^2 equivalent to 2x^2+8x+8? Explain or show your reasoning.
answer: no because they have different x values

(x + 4) 2 —> 2x + 8

2 x 2 + 8x + 8 —> 8x + 12

teachers response:

Your answer is correct in that they are not equivalent. But I need you to show me what (x+4)^2 equals. First, you would write it this way: (x+4) (x+4). Now, multiply these binomials…what do you get?

The expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

What is an equivalent?

The equivalent is the expression that is in different forms but is equal to the same value.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (x + 4)²

Simplify the expression, then we have

⇒ (x + 4)²

⇒ (x + 4)(x + 4)

⇒ x² + 8x + 16

Thus, the expression (x + 4)² is not equivalent to the expression 2x² + 8x + 8.

More about the equivalent link is given below.

Factor each polynomial using the Greatest Common Factor. ​

Answers

Answer:

–9(3x³ – 8x + 9)

Step-by-step explanation:

–27x³ + 72x – 81

The above equation can be factorised as follow:

–27x³ = –3 * 3 * 3 * x * x * x

72x = 2 * 2 * 2 * 3 * 3 * x

–81 = –3 * 3 * 3 * 3

Common factor = 3 * 3

Greatest common factor = 9

Thus,

–27x³ + 72x – 81 = 9(–3x³ + 8x – 9)

–27x³ + 72x – 81 = –9(3x³ – 8x + 9)

It was the evident wish and will of Parliament and the nation that this should be conceived on the broadest possible basis and that it should include all parties, both those who supported the late Government and also the parties of the Opposition. I have completed the most important part of this task. A War Cabinet has been formed of five Members, representing, with the Liberal Opposition, the unity of the nation. 2 The three party Leaders have agreed to serve, either in the War Cabinet or in high executive office. The three Fighting Services have been filled. It was necessary that this should be done in one single day, on account of the extreme urgency and rigor of events. A number of other key positions were filled yesterday, and I am submitting a further list to His Majesty tonight. I hope to complete the appointment of the principal Ministers during tomorrow. The appointment of the other Ministers usually takes a little longer, but I trust that when Parliament meets again, this part of my task will be completed, and that the administration will be complete in all respects. 3 Sir, I considered it in the public interest to suggest that the House should be summoned to meet today. Mr. Speaker agreed, and took the necessary steps, in accordance with the powers conferred upon him by the Resolution of the House. At the end of the proceedings today, the Adjournment of the House will be proposed until Tuesday, the 21st of May, with, of course, provision for earlier meeting, if need be. The business to be considered during that week will be notified to Members at the earliest opportunity. I now invite the House, by the Resolution which stands in my name, to record its approval of the steps taken and to declare its confidence in the new Government. CLOSING 4 We have before us an ordeal of the most grievous kind. We have before us many, many long months of struggle and of suffering. You ask, what is our policy? I will say: It is to wage war, by sea, land and air, with all our might and with all the strength that God can give us; to wage war against a monstrous tyranny, never surpassed in the dark and lamentable catalogue of human crime. That is our policy. You ask, what is our aim? I can answer in one word: victory; victory at all costs, victory in spite of all terror, victory, however long and hard the road may be; for without victory, there is no survival. Let that be realized; no survival for the British Empire, no survival for all that the British Empire has stood for, no survival for the urge and impulse of the ages, that mankind will move forward towards its goal. But I take up my task with buoyancy and hope. I feel sure that our cause will not be suffered to fail among men. At this time I feel entitled to claim the aid of all, and I say, "Come then, let us go forward together with our united strength."A) the author has the goal of preparing the British for an invasion, and he knows he will have to answer a lot of questions from the people after his speech.
