Answer:

Step-by-step explanation:

Given,

Length (l) = 2(7z + 3) = 14z + 6

Breadth (b) = 5z

Now,

Perimeter of rectangle (P) = 2(l + b)

                                           =2(14z + 6 + 5z)

                                           =2(19z + 6)

                                           =38z + 12

PLEASE HELP ive been stuck on this for a long time
Tomtit [17]

Answer:

Below

Step-by-step explanation:

You can use Pythagorean theorem to find the hypotenuse of a right triangle.

a2 + b2 = c2

The square root of 15 = 3.8729.... (a bunch of other numbers)

4^2 + 3.8729^2 = c2

16 + 15 = 31

Now that you have this, you need to find the square root

The square root of 31 = 5.56775436

Rounding this to the tenth it would be: 5.57

Final answer: C = 5.57

hope this helps! :)

Given f(x)=3x^3+2x+k and x+1 is a factor of f(x) then what is the value of k
yaroslaw [1]

Answer:

k = 5

Step-by-step explanation:

Given that (x + 1) is a factor of f(x) then f(- 1) = 0

f(- 1) = 3(- 1)³ + 2(- 1) + k

      = 3(- 1) - 2 + k

     = - 3 - 2 + k

    = - 5 + k

Then - 5 + k = 0 ( add 5 to both sides )

k = 5

A pizza stand offers both hand-tossed and pan pizza. Customers can add any combination of the six available toppings.
damaskus [11]

Answer:

a)14 or b)74

Step-by-step explanation:

I'm assuming the question is how many combinations are there.

A) If toppings can't stack it would be 14, since there are 6 toppings for 2 pies and also you can go without toppings. or *2

B) If toppings can stack, then there can be 74 from being able to stack 6 toppings on one pizza and then two pizzas without it or (6^2)*2+2
