Answer:
<u>16 cm²</u>
Step-by-step explanation:
A cube has 12 edges.
Therefore, length of each edge
= 48/12
= 4 cm
Area of face = edge x edge
= 4 x 4
= <u>16 cm²</u>
Answer:
Therefore the x-intercept of

is

Step-by-step explanation:
Intercepts:
The line which intersect on x-axis and y-axis are called intercepts.
There are two intercepts:
y-intercept: The line which intersect at y-axis. So when the line intersect at y-axis X coordinate is zero.
x-intercept: The line which intersect at x-axis. So when the line intersect at x-axis Y coordinate is zero.
For x-intercept of y = 3x² + 6x + 3
put y = 0

Dividing throughout by 3 we get


Which is nothing but in the identity form of (A+B)² = A² +2AB +B²
A = x
B = 1
Therefore Equation becomes

Therefore the x-intercept of

is

The coordinates of point D is (0, 7)
<h3><u>solution:</u></h3>
The midpoint M of CD has coordinates (2, 5)
Point C has coordinates (4, 3)
To find: coordinates of point D
The midpoint of line AB conatining points
and
is given as:

Here in this problem,
Midpoint (C, D) = (2, 5)


Subsituting the values in formula we get,

On comparing both the sides we get,


Thus the coordinates of point D is (0, 7)
