Answer C

Step-by-step explanation:

Answer:

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]

Hence, option D is correct.          

Step-by-step explanation:

We have to subtract (4x² - x + 6) from (3x² + 5x - 8).

so

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)[/tex]

Remove parentheses: [tex]\left(a\right)=a[/tex]

[tex]=3x^2+5x-8-\left(4x^2-x+6\right)[/tex]

[tex]=3x^2+5x-8-4x^2+x-6[/tex]

Group like terms

[tex]=3x^2-4x^2+5x+x-8-6[/tex]

Add similar elements:  [tex]\:3x^2-4x^2=-x^2[/tex]

[tex]=-x^2+5x+x-8-6[/tex]

Add similar elements:  [tex]5x+x=6x[/tex]

[tex]=-x^2+6x-8-6[/tex]

Subtract the numbers: [tex]-8-6=-14[/tex]

[tex]=-x^2+6x-14[/tex]

Therefore,

[tex]\left(3x^2+5x-8\right)-\left(4x^2-x+6\right)=-x^2+6x-14[/tex]

Hence, option D is correct.

Answer:

[tex]x=54.6[/tex]

Step-by-step explanation:

Because ΔABC is similar to ΔSTU, we know that their corresponding sides are proportional. Therefore, we know that [tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]. We are given that [tex]AB=x[/tex], [tex]AC=21[/tex], [tex]SU=13[/tex], and [tex]ST=5[/tex]. After substituting the given values into the proportion and solving for [tex]x[/tex], we get:

[tex]\frac{AB}{AC}=\frac{SU}{ST}[/tex]

[tex]\frac{x}{21} =\frac{13}{5}[/tex] (Substitute given values into the proportion)

[tex]5*x=13*21[/tex] (Cross-Products Property)

[tex]5x=273[/tex] (Simplify)

[tex]\frac{5x}{5}=\frac{273}{5}[/tex] (Divide both sides of the equation by [tex]5[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=54.6[/tex] (Simplify)

Hope this helps!

Answer:

x=55

Step-by-step explanation:

these are similar triangles(they have same shape and different sizes)

also two side of these triangles are equal.

lets write ratio:

21:5=x:13

x=21×13/5=54.6≈55

Answer:

The correct answer is: -7, 7

Step-by-step explanation:

Given numbers are:

-7, 0, 7, 14

We have to check all pairs of numbers with respect to sum to check that which pair of numbers sums up to zero. So first of all, we will take -7 and will find its sum with other numbers.

So,

[tex]-7+0 = -7\\-7+7=0\\-7+14 = 7[/tex]

We can see that the sum of -7 and 7 is zero.

Hence,

The correct answer is: -7, 7

Your answer is B.) -7, 7

Answer:

f(10) = 6

Step-by-step explanation:

To evaluate f(10), substitute x = 10 into f(x), that is

f(10) = 10 - 4 = 6

Answer:

$0.216 and $0.293

Step-by-step explanation:

Given,

Price club sells 12 ounce box = $2.59

Shop mart sells a 1 pound box = $ 4.68.

We have to find the unit price at Price club and Shop mart.

We know that 1 Pound = 16 ounce

Unit price at Price-club = [tex]\dfrac{2.59}{12}[/tex]

                                      = $0.216

Unit price at Shop Mart= [tex]\dfrac{4.68}{16}[/tex]

                                      = $0.293

because I got this question too. On odysse.yware.

Answer:

0.21 and 0.19

Step-by-step explanation:

It's simple, just divide it.

Divide 2.59 by 12 and divide 4.68. Then round the answers to the closest number in the choices. That's your answer buddy!

Question B

Answer:

25km/hr (take the word train as bus )

Step-by-step explanation:

Answer

Let x km/hr be the constant speed of the train,

Then Time taken to cover 300km=

x

300

hrs

Time taken to cover 300km when the speed is increased by 5km/hr=

x+5

300

hours

It is given that the time to cover 300km is reduced by 2 hours

∴

x

300

−

x+5

300

=2

⇒

x(x+5)

300(x+5)−300x

=2⇒2x

2

+10x=1500

⇒x

2

+5x−750=0⇒x

2

+30x−25x−750=0

⇒(x+30)(x−25)=0⇒x=25orx=−30

But x cannot be negative. Therefore x=25

Hence, the original speed of the train is 25km/hr

Answer:

Step-by-step explanation:

3/8 if you change 1/4 to 8ths you get 2/8. so if you add 1 3/8 + 2/8 you get 1 5/8 so you only need 3/8 to get to 2 quarts.

Answer:

Sierra's profit was $41.

Step-by-step explanation:

Sierra realized she lost two-third of a dollar each hour when the shop was closed.

The expression that models this situation is,  ............. (1)

Now, we have to calculate Sierra's profit if the shop was closed for 6 hours.

So, putting h = 6 hours in the equation (1) we get,

dollars.

So, Sierra's profit was $41. (Answer)

Answer:

b=-1

Step-by-step explanation:

First step to any algebraic equation is to combine like-terms. This would mean that we would have to subtract 4b from both sides, I'm assuming its supposed to be plus ten and you just typed it wrong but, we get 5b+15=10 here we  subtract 15 from both sides and get 5b=-5. Now we isolate the variable b, getting b=-1.

Step-by-step explanation:

Answer: [tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]

Step-by-step explanation:

[tex]w^{2} + 13w + 36 = (w + 4)(w + ?)[/tex]

w (w + ?) +4 (w + ?)

w² + ?w + 4w + ?

4w + ?w = 13w

Subtract both sides by 4w

?w = 9w

? = 9

4 (?) = 36

Divide both sides by 4

? = 9

[tex]w^{2} + 13w + 36 = (w + 4)(w + 9)[/tex]

Answer:

[tex]\frac{2}{3}[/tex]

Explanation:

What we need to do is to convert [tex]\frac{8}{12}[/tex] into a new - but still equal - fraction, one with a denominator of 3. In order to convert a fraction, you either divide or multiply both the denominator and the numerator by the same number.

We know that the answer has to be a fraction with the denominator of 3. Take a look at the denominator of [tex]\frac{8}{12}[/tex] - it's 12. Ask yourself: 12 divided by what number equals 3? That number would 4.

So, divide 8 by 4 as well and you would get 2. Therefore, the numerator would be 2 and the answer is [tex]\frac{2}{3}[/tex].
