choose all that apply 13^6+(13^8)(13^-4)/13^-2

Answer: -5/3

Step-by-step explanation:

12(b + 2) + 3b = -1

12b + 24 + 3b = -1

15b + 24 = -1

15b = -1-24

b = -25/15 = -5/3

The solution to the equation 12(b+2) + 3b = -1 is b = -5/3.

Given the equation in the question:

12( b + 2 ) + 3b = -1

To solve the equation 12( b + 2 ) + 3b = -1, first apply the distributive property.

Distribute the 12 across the terms inside the parentheses:

12( b + 2 ) + 3b = -1

12×b + 12×2 + 3b = -1

Simplifying, we get:

12b + 24 + 3b = -1

Collect and combine the like terms on the left side of the equation:

12b + 3b + 24 = -1

15b + 24 = -1

Subtract 24 from both sides of the equation:

15b + 24 - 24 = -1 - 24

15b = -1 - 24

15b = -25

Divide both sides by 15:

b = -25/15

Simplify

b = -5/3

Therefore, the value of b is -5/3.

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Answer:

Other answer is incorrect. Elijah's new balance would be $322.59

Your welcome.

Answer:

For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula

Step-by-step explanation:

The great pyramid of Cheops is a square based pyramid therefore we have;

V + F = E + 2

Where:

V = Vertices

F = Faces

E = Edges

Hence, we have for a square pyramid;

V = 5 vertices (One at the peak, and four  at the base edges)

F = 5 faces (The four lateral or side faces and the base)

E = 8 edges ( The four lateral edges and the four base edges)

Hence;

5 + 5 = 8 + 2 which proves Euler-Descartes formula.

Answer:

The area of the trapezoid would be 115 inches.

Answer:

x=20 and y=128.Option 2

Step-by-step explanation:

Since,the angles are vertically opposite,they are equal(property)

Therefore,

(3x-8)=(2x+12)

3x-8=2x+12

3x-2x=12+8

x=20,

Now,

Since,the angles are formed in a straight line,their sum is equal to 180(property)

Therefore,

y+(2x+12)=180

y+2×20=180-12

y=168-40

y=128

Therefore,x=20 and y=128

option 2 would be your answer because it explains the missing part where y is.

Answer:

11.3

Step-by-step explanation:

i used the theorem of Pythagoras

Answer:

11.3

Step-by-step explanation:

In a right angled triangle:  the square of the hypotenuse is equal to

the sum of the squares of the other two sides.

[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)

64 + 64 = [tex]x^{2}[/tex]

[tex]x^{2}[/tex] = 128

=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3

Answer:

The twentieth term is 50.

Step-by-step explanation:

The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:

a1 = 3*1 - 10

a1 = -7

Therefore to find the twentieth term we need to make n equal to 20. This is done below:

a20 = 3*20 - 10

a20 = 60 - 10

a20 = 50

The twentieth term is 50.
