Mathematics
1 answer:
cupoosta [38]3 years ago
5 0

Answer:

B

Step-by-step explanation:

Subtract 20 from both sides:

-\sqrt{9-8x} =-15

Divide both sides by -1:

\sqrt{9-8x} =15

Square both sides:

9-8x=255

Subtract 9 by both sides:

-8x=216

Divide both sides by -8:

x=-27

That means that either a or b is correct and since 9/8 is positive that means it needs to bee less than 9/8 so the correct answer is B

Write 4x2(–2x2 + 5x3) in standard form. Then classify it by degree and number of terms.
umka2103 [35]
20x^5-8x^4 polynomial of the 5th degree, with two terms.

Distribute 4x^2(–2x^2 + 5x^3) to get –8x^2 + 20x^5. Reorder in standard form 20x^5-8x^4.  5 is the highest exponent so it is the 5th degree, there are two terms because terms are separated by a plus or minus.
