Answer:

B. ) x² + 4x + 3

Step-by-step explanation:

(f-g)(x) = f(x) - g(x) =

(2x²-5) - (x²-4x-8) =

2x² - x² + 4x + 8 - 5 =

(02.05 MC) A dance school has 63 ballet dancers. If 42% of the total number of dancers in the school are ballet dancers, what is

Elena L [17]

Alright, lets get started.

Suppose total number of dancers in school = x

We have given in question, 42 % of total dancers are ballet dancers.

So, we could find number of ballet dancers by finding 42 % of total dancers.

Number of ballet dancers = x * 42 %

Number of ballet dancers = x * 42/100 = 0.42 x

As per given in question, there are 63 ballet dancers in school.

Which means 0.42 x = 63

Dividing 0.42 from both sides

0.42 x / 0.42 = 63 / 0.42

x = 150

Hence number of total dancers in school = 150 : Answer

Hope it will help :)

Find four consecutive even integers so that the sum of the first three is 2 more than twice the fourth

scoundrel [369]

Answer:

The numbers are : -20,-18,-16,-14

Step-by-step explanation:

Let 1st even integer be $=x$

So, next consecutive even integer would be $=x+2$

3rd consecutive even integer would be $=x+4$

4th consecutive even integer would be $=x+6$

Sum of first three integers would be $=x+x+2+x+4=3x+6$

It says sum of the first three is 2 more than twice the fourth,

So we have

$3x+6=2+4(x+6)$

using distribution to simplify.

$3x+6=2+(4\times x)+(4\times6)$

$3x+6=2+4x+24$

$3x+6=4x+26$

Subtracting $4x$ from both sides

$3x+6-4x=4x+26-4x$

$-x+6=26$

Subtracting 6 from both sides

$-x+6-6=26-6$

$-x=20$

∴ $x=-20$

So first integer =-20

2nd integer $=-20+2=-18$

3rd integer $=-18+2=-16$

4th integer $=-16+2=-14$

So, the numbers are : -20,-18,-16,-14
