The Fibonacci sequence works like this. Take the first two generations, add them together and that gives you the third. Add the second and third to get the fourth. Add the fourth and fifth to get the sixth.

So you need to add the sixth and seventh to get the eighth.
13 + 21= 34

Add the seventh and eighth to get the ninth.
21 + 34= 55

Answer is C- 34, 55

sergey [27]

Because it is an isosceles triangle, the two longer sides are the same length. Therefore multiply 6.3 times 2.
To find the length of the base subtract 12.6 from 15.7 to get 3.1 cm.

Devon made a box with length x+1, width x+3, and height x-3. What is the volume of Devon's box as a function of x?

erica [24]

Answer:

(a)

$V=x^3+x^2-9x-9$

(b)

$x=10$

(c)

$x=\frac{7}{2}$

Step-by-step explanation:

we are given

length is x+1

$L=x+1$

width is x+3

$W=x+3$

height is x-3

$H=x-3$

(a)

we can use volume formula

$V=L\times W\times H$

now, we can plug it

$V=(x+1)\times (x+3)\times (x-3)$

now, we can simplify it

$V=x^3+x^2-9x-9$

(b)

we are given volume =1001

so, we can set V=1001

and then we can solve for x

$V=x^3+x^2-9x-9=1001$

now, we can factor it

$\left(x-10\right)\left(x^2+11x+101\right)=0$

$x-10=0$

$x=10$

(b)

we are given volume

so, we can set

$V=14\frac{5}{8}=\frac{14\times 8+5}{8}$

$V=\frac{117}{8}$

and then we can solve for x

$V=x^3+x^2-9x-9=\frac{117}{8}$

now, we can factor it

$8x^3+8x^2-72x-189=0$

$\left(2x-7\right)\left(4x^2+18x+27\right)=0$

$2x-7=0$

$x=\frac{7}{2}$

A man wants to paint his room with an area of 515 square feet. He mixses the following paints to make a shade of green

larisa [96]

About 3 gallons of blue paint will be needed because if you add 175+175 it equals 350 and then add another 175 it equals 525.

What is the perimeter of a square if it has an area of 36 square centimeters?

kirill115 [55]

Let x is the side of the square
so A = x * x or A = x^2 = 36
As you know 36 is a perfect square root = 6^2
Then x = 6 cm

Perimeter = 4x = 4(6) = 24 cm
