2x - 4x = -8
-2x = -8
x = 4

First add like terms
-8 - x = -3x
-8 = -2x   [added x to both sides]
x = 4      [divided both sides by -2]

therefore  x = 4

1. What would the polynomial x + 7 – 4x^3 be written as in standard form?
yarga [219]
Hello there!

The only thing we need to do to get this polynomial in standard form is rearrange the terms!

x+7-4x^3
-4x^3+x+7 is the polynomial written in standard form. Remember to keep track of the negatives!

The GCF of the polynomial
24x^5+18x^9 is...
6x^5
Because it is the greatest term that goes into both 24x^5 AND 18x^9!
This will end up helping you factor later on.
6x^5(4+3x^4)

I really hope this helps!
Best wishes :)

#7-9 please help with an explanation,, will mark brainliest
Mandarinka [93]

Answers:

<h2>7. 12</h2><h2>8. -√18</h2><h2>9. √220</h2>

Step-by-step explanation:

To find out which is greater, we must eliminate the radical symbol.

#7

\sqrt{88} = 9.38083151965

9.4 < 12

#8

-\sqrt{18} = -4.24264068712

-4.2 > -6

#9

\sqrt{220} = 14.8323969742

14.5 < 14.8

I'm always happy to help :)
