Answer:

Option B is correct

Explanation:

Value of a is -3

Given the equation:   \frac{24x^2+25x-47}{ax-2} =-8x-3-\frac{53}{ax-2} is true for all x\neq 2a

To find the value of a.

Multiply both sides of the given equation by (ax-2), we have;

 24x^2+25x-47=(-8x-3)(ax-2)-53

Using FOIL Method to multiply two binomials i.e (-8x-3)(ax-2)

24x^2+25x-47=-8ax^2+16x-3ax+6-53

or

24x^2+25x-47=-8ax^2+x(16-3a)-47

Since the coefficients of the x^2 term have to be equal on both sides of the equation. we have;

-8a = 24

Divide both sides by -8 we get;

a = -3

Therefore, the value of a is, -3

Which type of burn is BEST described as having reddish skin, white border, and some pain? A. first-degree burn B. second-degree
alexgriva [62]

Answer:

I believe it's B - Second-Degree Burns

Explanation:

A first degree burn would be like keeping your finger over a flame for a little too long, it'll cause red skin and some pain, but not the white boarder. Third degree burns would be like holding onto metal left in burning temperatures, touching lava, it'll burn all the way down to the fat tissue, causing emese pain. Fourth degree burns are horrible, the skin turns black, it burns past the fat tissue, no way it would cause only "some" pain

scientists say that researching genes will help find solutions for diseases that affect humans. is this true? Give reasons for y
Nataliya [291]
When genetic molecules are broken down and deciphered under a large scale then the defects can be magnified and researched and further stopped. Hopefully with the scientific advancements at hand and with enough people to come forward to participate in the study these diseases and genetic defaults will cease.
