The x co-ordinate of any point lying on the Y axis is: please help urgent​
olchik [2.2K]

Answer:

x-coordinate = 0

Step-by-step explanation:

In a coordinate plan there are two perpendicular lines one is x-axis and another is y-axis

x-axis is a horizontal line and y-axis is a vertical line.

Both lines intersect each other at (0,0).

On x-axis, y-coordinate remains same , i.e., y=0.

On y-axis, x-coordinate remains same , i.e., x=0.

Therefore, the x co-ordinate of any point lying on the y axis is 0.

Given that x2 - y2 = 135 and x - y = 15 , find the value of (x+y)2
kirill [66]

Answer:

x² - y² = 135

<=> (x - y)(x + y) = 135

<=> 15(x + y) = 135

=> x + y = 135/15 = 9

=> (x + y)² = 81

(a) Draw the net of a cube with sides 4 cm;
Lemur [1.5K]
A) draw a cube
i) 16cm
ii) 80 cm
b)64 cm
Ok so draw the outline of a cube with 4cm each. There is six sides and the area is just multiplying 4 by 4. So, since the area of each side is 16, and there is 6 sides, the surface area is 80 cm. The volume is just length x width x height (4x4x4) so it’s 64 cm cubed.
