4x - 5y = -12
-x + 5y = 18
Add the equations together:
4x + -x = 3x
-5y + 5y = 0
-12 + 18 = 6
So now you have:
3x = 6
Divide both sides by 3:
X = 2
Now you have the value of x, replace x with 2 in one of the equations and solve for y:
4(2) -5y = -12
8 -5y = -12
Subtract 8 from both sides:
-5y = -20
Divide both sides by -5:
Y = 4
The solution is x = 2 and y = 4 which is written as (2,4)
The factored form for this question is (5x-1)(x-5)

The expression of Volume in cubic meter
(8)(6)(6)+(8)(6)(4)
The correct option is (1)
<h3>What is Volume?</h3>
Volume can also be defined as the amount of space occupied by a 3-dimensional object. The volume of a solid like a cube or a cuboid is measured by counting the number of unit cubes it contains.
Volume will be,
V= Volume of rectangular pyramid + Volume of cuboid
Volume of rectangular pyramid=
* base area* height
=
* 6*8*(10-4)
=
* 6*8*6
Volume of cuboid= l*b*h
= 4*6*8
So, Volume =
* 6*8*6 + 4*6*8
=
(8)(6)(6)+(8)(6)(4)
So, The expression of Volume in cubic meter
(8)(6)(6)+(8)(6)(4).
