Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither
Step-by-step explanation:
Let the width=x
Length =6x-4
As we know that in a rectangle




- Here a=6, b=-4, c=-20.
- use quadratic formula

Step-by-step explanation:
<em>Given: Side lengths of a right triangle 3,4 and 5 units.
</em>
<em>
To draw: A right triangle with the given side length.
</em>
<em>
Solution:
</em>
<em>
We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem.
</em>
<em>
From the given side length,
</em>
<em>
Hypotenuse = 5 unit
</em>
<em>
We can take any of the base and perpendicular.
</em>
<em>
Let, Base = 3 unit
</em>
<em>
Perpendicular = 4 unit.
</em>
<em>
It a right-angle triangle with a hypotenuse 5 unit.
</em>
<em>
Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.</em>
