If a figure has elght vertices and 12 edges, how many faces does it have? 10
8
6
4

Answers

Answer 1

Answer:

It would have 6 faces

Step-by-step explanation:

In any convex polyhedron:

let v be the number  vertices , e is the number of edges and f is the number of faces then;

             ....[1]

As per the statement:

If a figure has eight vertices and 12 edges

⇒v = 8 and e = 12

Substitute in [1] to solve for f, we have;

⇒

Subtract 6 from both sides we have;

f = 6

Answer: Second option, 2^2x+6=2^6

Step-by-step explanation:

You can simplify 4^x+3 by making the 4 into 2^2. By doing this you also multiply the current powers of 4 by 2, giving you (x+3) • 2, furthermore, 2^2x+6.

64 is a power of 2, so just multiply 2 by itself until you get the number you’re looking for and count how many times you do it. Or just type each option, like 2^4, 2^6 into the calculator until you find it.

A carpenter uses two different types of paint in his work, X-Brand and Y-Brand (represented by the x and y variables respectively in the system of equations below). The system of equations represents the total cost and amount of paint he purchased for a client. Determine the cost, in dollars, of the X-Brand.
2x+5y=6
−x+2y=−3

Answers

Answer

$3

Step-by-step explanation:

To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you

4x+10y=12

5x-10y=15

You can then cancel out the y terms and add the other terms from the 2 equations together to make

9x=27

You then divide 27 by 9 to get 3 as the value for x.

a. What is mZw?

Answers

w= 55
z= 55

for w take 90+35 then your answer minus 180 which would equal 55. w and y are vertical angles therefore you can add 55+70 and get 125, 180-125= 55, so 55 would be the answer for both w and z
