14*14*6/3 = 196*2=392

24*24*16/3=8*24*16=3072

15*5*7 + 15*5*13/3 = 15*35+25*13= 850

Last one plz help guys

ohaa [14]

Answer:

4.1

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this:

$a^{2} + b^{2} = c^{2}$

Plug in the numbers into the formula:

$4^{2} + 1^{2} = c^{2}$

16 + 1 = $c^{2}$

17 = $c^{2}$

Square both sides:

$\sqrt{17} = \sqrt{c^2}$

4.12 = c

4.1 = c

A flower bed is in the shape of a triangle with one side twice the length of the shortest side, and the third side is 14 feet mo

umka21 [38]

Answer:

The dimensions of triangle are 66 ft, 33 ft and 47 ft

Step-by-step explanation:

Let

x -----> the length of one side

y -----> the length of the shortest side

z -----> the length of the third side

we know that

The perimeter of triangle is

$P=x+y+z$

$P=146\ ft$

$146=x+y+z$ -----> equation A

$x=2y$ -----> equation B

$z=y+14$ ----> equation C

Substitute equation B and C in equation A and solve for y

$146=2y+y+y+14$

$146=4y+14$

$4y=146-14$

$4y=132$

$y=33\ ft$

Find the value of x

$x=2(33)=66\ ft$

Find the value of z

$z=33+14=47\ ft$

therefore

The dimensions of triangle are 66 ft, 33 ft and 47 ft
