Answer:
x=-5, y=-2
Step-by-step explanation:
3x+2y= -19
-3x-5y= 25
Add the two equations together
3x+2y= -19
-3x-5y= 25
------------------
0x -3y = 6
Divide each side by -3
-3y/-3 = 6/-3
y = -2
Now find x
3x+2y = -19
3x +2(-2) =-19
3x-4 = -19
Add 4 to each side
3x -4+4 = -19+4
3x= -15
divide by 3
3x/3 = -15/3
x = -5
A cube is a three-dimensional solid object having six square faces. The measure of the length of the diagonal of the face of the cube is 12.2 cm.
<h3>What is a cube?</h3>
A cube is a three-dimensional solid object having six square faces, facets, or sides, three of which meet at each vertex. The cube is one of the five Platonic solids and the only regular hexahedron.
Given the length of an edge of the cube is √75 cm, therefore, the length of the diagonal of the face of the cube will be √2 times the length of an edge of the cube. Thus, the measure of the length of the diagonal of the face of the cube is,
Length of the diagonal of the face = √2 × √75 = 12.2 cm
Hence, the measure of the length of the diagonal of the face of the cube is 12.2 cm.
