Answer:

5n + 1

Step-by-step explanation:

f(n) + g(n) is just 2n + 1 + 3n , adding the two functions together!

Those expressions combine to 5n + 1 :)

Answer:

that angle is 45°

so y = 5√3

and × = √2×y

x= √2 × 5√3

x=5√6

Answer:

1. if you are solving using the quadratic formula. the answer is in the first picture.

2. if you are looking to completing the square the answer is in the second picture.

Step-by-step explanation:

Answer:

zeros are ±2

Step-by-step explanation:

y = x² - 4

this can be factored into (x+2)(x-2)

if you then set each factor equal to zero you will get zeros of ±2

Answer:

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

Answer:

5280

Step-by-step explanation:

Hope this helps!

Answer:

Step-by-step explanation:

a systems of equations can be made from the information on the problem

x+y=48

x=2y+3

since x= 2y+3 substitute 2y+3 in the firat equation to get:

(2y+3)+y=48  -> 3y+3=48 -> 3y=45  -> y=15

plug in 15 for y in the second equation to solve for x

x+15 =48 --> x=33

Answer:

(x+5) metres

Step-by-step explanation:

correct question

The rectangle below has an area of x^2+8x+15 square meters and a width of x+3 meters. What expression represents the length of the rectangle?

Area of the rectangle = Length * width

Factorize the area

A(x) =  x^2+8x+15

A(x) = x^2+3x+5x+15

A(x) = x(x+3) + 5(x+3)

A(x) = (x+3)(x+5)

Since the width is x+3, the length of the rectangle will be (x+5) metres

a^2 is correct

my past answer was incorrect but this 100 percent is correct

Answer:

3^12

when we see a number above a number in roots we Multiply

then we will find 3¹⁰/3-² in devide we Take number so its 10-(-2)=12

hopefully its helpful

Answer:

3^12 hope this helped :)

Step-by-step explanation:

(3^5)^2 = 3^10

3^10 ÷ 3^-2

10--2=12

6000 milligrams

Step-by-step explanation:

Let A be the first sequence, and denote by [tex]a_n[/tex] the n-th term in A.

Consider the forward differences of A :

16 - 7 = 9

30 - 16 = 14

49 - 30 = 19

73 - 49 = 24

Call this sequence of first differences B, so that for n ≥ 1,

[tex]b_n=a_{n+1}-a_n[/tex]

where [tex]b_n[/tex] is the n-th term of B.

Now consider the forward differences of B, which is another sequence we'll call C :

14 - 9 = 5

19 - 14 = 5

24 - 19 = 5

Then if [tex]c_n[/tex] is the n-th term of C, we have for all n ≥ 1,

[tex]c_n=b_{n+1}-b_n=5[/tex]

which gives

[tex]b_{n+1} = b_n+5[/tex]

This tells us B is an arithmetic sequence - the first term is 9 and the difference between consecutive terms is 5, so we have for n ≥ 1,

[tex]b_n = 9 + 5(n-1) = 5n + 4[/tex]

Plug this into the recurrence for A :

[tex]a_{n+1} = a_n + b_n = a_n + 5n + 4[/tex]

We don't need to solve for [tex]a_n[/tex], fortunately; we just want the next term, which would be

[tex]a_6 = a_5 + 5^2 + 4 = 73 + 25 + 4 = \boxed{102}[/tex]

Answer:

Step-by-step explanation:

[tex]\left(6-5x^2\right)\left(x^4-x^3\right)\\\\\mathrm{Apply\:FOIL\:method}:\\\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd\\\\a=6,\:b=-5x^2,\:c=x^4,\:d=-x^3\\\\=6x^4+6\left(-x^3\right)+\left(-5x^2\right)x^4+\left(-5x^2\right)\left(-x^3\right)\\\\\mathrm{Apply\:minus-plus\:rules}\\+\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab\\\\=6x^4-6x^3-5x^4x^2+5x^3x^2\\\\Simplify\\\\=-5x^6+5x^5+6x^4-6x^3[/tex]

Answer:

they would be $42.00

Step-by-step explanation:

50 + 2.50= 52.50

52.50-10.50=42.00

Answer:

area = 186.984

Step-by-step explanation:

The 3 rectangular surfaces are simply L * W of each so

left surface = 5.5 * 6.2 = 34.1

right surface = 5.5 * 8.5 = 46.75

bottom surface = 5.5 * 9.8 = 53.9

The front and back are the same so

front = 1/2 base * heigth = 1/2 * 9.8 * 5.33 = 26.117

front + back = 2 * 26.117 = 52.234

total = sum them all up = 34.1 + 46.75 + 53.9 + 52.234 = 186.984
