Volume of A = 1728

volume of B = 729

(1728 / 729) = (a / b)^3 (a = width of A, b = width of B)
a / b = cube root (1728 / 729) = 4/3 b = 10 (given)
a / 10 = 4/3 
a = 40/3 = 13.33333
so width of A is 13.33m

Answer:

Factorized

$=(2x-8)(x-3)$

Roots : 4 , 3

Step-by-step explanation:

If it is to factorize :

$2x^2 - 14x + 24 = 2x^2 -6x-8x +24$

$=2x(x-3)-8(x-3)\\=(2x-8)(x-3)$

If it is to solve for x :

$2x^2 -1 4x + 24 = 0\\(2x-8)(x-3)=0\\2x - 8 = 0 \ , \ x - 3 = 0\\2x = 8 \ , \ x = 3\\x = 4 , 3$

What is x and y equal in: -2X-y=3 and x+2y=4 (find x and y using elimination)

makvit [3.9K]

-2x-y=3 ...(1)
x+2y=4 ...(2)
multiply (2) by 2 and add to (1)
-2x-y+2x+4y=3+8
3y=11
y=11/3
from (2)
x=4-2y=4-2(11/3)
or x=4-(22/3)
=(12-22)/3=-10/3

Equation for x small balloons and y large balloons

2x + 4y

Total cost of 10 small balloons and 5 large balloons

x = 10, y = 5

2(10) + 4(5)

= 20 + 20
