What is the answer here

Answer:

f(x) + g(x) = (-2x + 8)+ 3x

f(x) + g(x) = -2x + 8 + 3x   Combine like terms.

f(x) + g(x) = x + 8        

f(x) + g(x) = (f+g)(x) = x + 8

(f + g)(-1) = -1 + 8

(f + g)(-1) = 7

Answer:

Apply the distributive property to the expression to write an equivalent expression.

5x + 35

Complete the statements.

Find the GCF of

✔ 5x and 35

.

Now, factor out the GCF by dividing each term in the expression by

✔ 5

.

5x divided by the GCF is

✔ x

, and 35 divided by the GCF is

✔ 7

.

The equivalent expression is

✔ 5(x + 7)

.

The equivalent expression is 5(x + 7).

Here we need to apply the distributive property

The equation is 5x + 35

Now we have to determine the GCF by dividing the 5

So, it comes 5(x + 7).

Hence, we can conclude that The equivalent expression is 5(x + 7).

Answer:

$38

Step-by-step explanation:

I solved this by doing a proportion, 41.04/108 = x/100 to find the original price before the 8% tax. To solve this proportion you have to isolate the variable, so you would do the cross product and multiply (41.04 x 100) and have that equal to 108x. So then because you have 108x = 4104, isolate x by dividing by 108 and you get 38, thus $38.

You can also check your work by multiplying 38 by 0.08 to find the amount of sales tax added, and if you do this you will get the value $41.04.

A percentage is a number or ratio that represents a fraction of 100. 

If an item costs $41.04, including an 8% sales tax then the cost of the item before the tax is $37.76.

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50/100 = 1/2

20% = 20/100 = 1/5

25% = 25/100 = 1/4

10% = 10/100 = 1/10

5% = 5/100 = 1/20

We have,

Cost of an item including tax = $41.04

Sales tax = 8%

8% = 8/100

The cost of the item without the sales tax:

= 41.04 - (8% of 41.04)

= 41.04 - (8/100 x 41.04)

= 41.04 - 3.2832

= 37.76

Thus,

The cost of the item before the tax is $37.76.

A. (-3,0)

Step-by-step explanation: you have to set the equation y to zero and than calculate the x

--> (x + 2)(x2 + 4x+3) = 0

--> (x+2) = 0 and (x2 +4x + 3) =0

--> X = -2 and        D= (4² - 4*2*3) = 4

                                      X = (-4 + [tex]\sqrt{4}[/tex]) / 2 of  X = (-4 + [tex]\sqrt{4}[/tex]) / 2

Step-by-step explanation:

Answer:

The base is 24 cm long.

Step-by-step explanation:

Equations

Let's call

b= base of the triangle

h=height of the triangle

The base is 9 cm longer than the height, thus:

b = h + 9

The area of the triangle is:

[tex]\displaystyle A=\frac{bh}{2}[/tex]

[tex]\displaystyle A=\frac{(h+9)h}{2}[/tex]

And its value is 180:

[tex]\displaystyle \frac{(h+9)h}{2}=180[/tex]

Multiplying by 2:

[tex](h+9)h=360[/tex]

Operating:

[tex]h^2+9h-360=0[/tex]

Factoring:

[tex](h-15)(h+24)=0[/tex]

The only valid positive solution is:

h = 15 cm

And b = h + 9 = 24

b = 24 cm

The base is 24 cm long.
