Answer:
64 cm^3
Step-by-step explanation:
answer for question no 5
length , breadth and height of the cube are always equal .So
here length = 4 cm
volume of a cube = l^3
=4^3
=64 m^2
Answer:
A
Step-by-step explanation:
The coordinates are (3,5),(7,-3),(0,-5),(-3,-4) and (-6,1). So the correct option is A
Consider the complete question is "The equation of the line
is y=5x+1 and the equation of line
is 2y-10x+3=0. How can you show that these two lines are parallel?"
Given:
Equation of
is
.
Equation of
is
.
To show:
The these line as parallel.
Solution:
We have,
...(i)
...(ii)
Equation (ii) can be written as



...(iii)
Slope intercept form of a line is
...(iv)
where, m is slope and b is y-intercept.
On comparing (i) with (iv), we get slope of line
.
On comparing (iii) with (iv), we get slope of line
.
Since,
, therefore, lines
and
and parallel because slope of two parallel lines are always equal.
Hence proved.

The equation is 36 - 4x = 6.
Solution:
To write the equation without fraction.


The denominators must be same to add/subtract the fractions.
LCM of 1, 9 and 3 = 9.
Multiply first term by
and
by
to make the denominator same.



Multiply by 9 on both sides.

Both 9 in the numerator and denominator get canceled.
36 - 4x = 6
This term does not have fraction.
Hence the equation is 36 - 4x = 6.
