What is the missing expression? x 8 + 3x 5 = x5(_____)

2 answers:

6 0

The missing expression is clearly a part of the factored polynomial.

We have to factor the polynomial.

x⁸+3x⁵

Find the GCF between 1,3,x,5,8

The GCF is x⁵

Divide the polynomial by x⁵

x⁵(x³+3)

I'm assuming that x 8 = x⁸ and 3x 5 = 3x⁵.

So let's solve.

x⁸ + 3x⁵ = x⁵(____)
x⁸ + 3x⁵ = x⁵(x³ __)
x⁸ + 3x⁵ = x⁵(x³ + 3)

Therefore the missing expression is (x³ + 3)

The Bobcats had a win-loss record of 41-23 before their star player, Melissa, got injured. Melissa didn’t play in any more games

MrRissso [65]

Answer:

The win percentage decreased by 10%

Step-by-step explanation:

First you need to fin the total games played right before Melissa got Injured

41+23=64

Then you need to find the win percentage by making a fraction of wins over total games

wins/total games = 41/64 = 64%

Then you need to find the number of games played after Melissa got injured

54-41 = 13 wins

34-23 = 11 losses

13+11 = 24 total games played without Melissa

You find that win percentage similarly to the first time

wins/total games = 13/24 = 54%

Then you find the difference in the percentages and there you have it!!

64% - 54% = 10%

It decreased as well therefore the answer is...

It decreased by 10%

Solve x2 - 8x - 9 = 0. Rewrite the equation so that it is of the form x2 + bx = c.

barxatty [35]

Answer:

x=9,-1 and $x^2+(-8)x=9$

Explanation:

we have been given with the quadratic equation $x^2-8x-9$

we compare the given quadratic equation with general quadratic equation

general quadratic is $ax^2+bx+c=0$

from given quadratic equation a=1,b= -8,c= -9

substituting these values in the formula for discriminant $D=b^{2}-4ac$

$D=(-8)^2-4(1)(-9)=100$

Now, to find the value of x

Formula is $x=\frac{-b\pm\sqrt{D}}{2a}$

Now, substituting the values we will get

$x=\frac{-(-8)\pm\sqrt{100}} {2}= \frac{8\pm10}{2}=9,-1$

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of

$x^2+bx=c$

Seven-eighths equals 0.875 and is a(n) ___.

kirza4 [7]

Answer:

negative number

Step-by-step explanation:

Numerator is 125 as dividing makes 875/1000

Numerator is 0.875 we can divide again by 8.75/10

we find that 0.875 = 875/1000 is equivalent to 7/8

6. A rectangle has a perimeter of 62 feet. If its length is 9 feet longer than its width, find

Anastaziya [24]

Answer:

length = 20 ft, width = 11 ft

Step-by-step explanation:

let w be width, then length = w + 9

The opposite sides of a rectangle are equal , then

2w + 2(w + 9) = 62

2w + 2w + 18 = 62

4w + 18 = 62 ( subtract 18 from both sides )

4w = 44 ( divide both sides by 4 )

w = 11

and w + 9 = 11 + 9 = 20

then width = 11 ft and length = 20 ft
