Answer:

6 $x^{5}$ + 5x² - 2x + 3

Step-by-step explanation:

Given

( $x^{5}$ + 2x² - 4) - (-5 $x^{5}$ - 3x² + 2x - 7)

Remove the parenthesis on the first factor and distribute the second by - 1

= $x^{5}$ + 2x² - 4 + 5 $x^{5}$ + 3x² - 2x + 7 ← collect like terms

= 6 $x^{5}$ + 5x² - 2x + 3 ← in standard form

14 is 28% of what number

Sindrei [870]

'is' in mathematics means the equal sign
'of' in mathematics means the multiplication sign
the number can be any variable you chose it to be

$14 = \frac{28}{100} \times x$

Divide both sides by 28

$\frac{1}{2} = \frac{x}{100}$

Multiply by 100 on both sides to isolate 'x'

$\boxed{\bf{x=50}}$

14 is 28% of 200

Which of the following is the solution for the inequality below? -3x+2<8

Zepler [3.9K]

Answer:

x>-2

Step-by-step explanation:

First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)
