Option B;
A suitable x-coefficient for a quadratic function that factors into a perfect square has to be even.
Nonamiya [84]3 years ago
6 0

Answer:

Option B is correct.

Step-by-step explanation:

We will work with the formula : (a+b)^{2}

= a^{2}+2ab+b^{2}

Given polynomial is :

64x^{2} +49x+8

here a = \sqrt{64x^{2} } =8x

b = \sqrt{8}= 2\sqrt{2}

2ab = 2*8x*2\sqrt{2} =32\sqrt{2}x

Now, we can see that the middle term should be 32\sqrt{2} x but in the question, it is given 49x

So, option B is true that - The x^2 coefficient does permit the factoring, but the x coefficient does not permit the factoring.

Help!!!!!! Find x and y so the quadrilateral is a parallelogram.
iren [92.7K]

Answer:

Conclusion:

  • The value of x = 7
  • The value of y = 4

Step-by-step explanation:

Given

  • The parallelogram PQRS

We know that the diagonals of a parallelogram bisect each other.

Therefore,

  • RT = TP

Given RT = x and TP = 5x-28, so

x = 5x-28

5x = x+28

5x-x = 28

4x = 28

divide boh sides by 4

4x/4 = 28/4

x = 7

Thus, the value of x = 7

Similarly,

QT = TS

Given QT = 5y and TS = 2y+12, so

5y = 2y+12

5y-2y = 12

3y = 12

divide both sides by 3

3y/3 = 12/3

y = 4

Thus, the value of y = 4

Conclusion:

  • The value of x = 7
  • The value of y = 4

1/2 of the people in the clinic are men, 1/3 are elderly, how many people are not elderly or men?
Nostrana [21]

1/6 of the people are not elderly or men

<h3>How to determine the proportion?</h3>

The given parameters are:

Men = 1/2

Elderly = 1/3

The number of people that are not elderly or men are:

People = 1 - Men - Elderly

So, we have:

People = 1 - 1/2 - 1/3

Evaluate

People = 1/6

Hence, 1/6 of the people are not elderly or men

What is the slope of a line that is perpendicular to the line shown? (3,3) and (-3,-1)
4vir4ik [10]

Answer:

-3/2

Step-by-step explanation:

Using the slope formula, we can find the slope of the line shown

m = ( y2-y1)/(x2-x1)

    = ( -1-3)/(-3-3)

   = -4/-6

  = 2/3

A line that is perpendicular is the negative reciprocal

-1/ (2/3) = -3/2
