Step-by-step explanation:
- 2(a-b) its yr question
- 2 & (a-b)is in the form of multiply
- so, first multiply a by 2 it becomes 2a and - sign is greater so, it will be - as it is then multiply b by 2 it becomes 2b
- now write yr ans =2a-2b

Answer:
Step-by-step explanation:
How can you remember the formula?
Well, it helps to know it's the Pythagoras Theorem with something extra so it works for all triangles:
Pythagoras Theorem:
(only for Right-Angled Triangles) a2 + b2 = c2
Law of Cosines:
(for all triangles) a2 + b2 − 2ab cos(C) = c2
So, to remember it:
think "abc": a2 + b2 = c2,
then a 2nd "abc": 2ab cos(C),
and put them together: a2 + b2 − 2ab cos(C) = c2
Answer:

Step-by-step explanation:
The value of x is -0.01.
<h2>Linear system</h2>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
<h3>Simplification</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
The equation is 102x + 11 = (x + 6)2 – 2.
<h3>To find </h3>
The value of x.
<h3>How to find the value of x?</h3>
The equation is 102x + 11 = (x + 6)2 – 2.
On simplifying,
102x + 11 = 2(x + 6) - 2
102x + 11 = 2x + 12 - 2
102x + 11 = 2x + 10
102x - 2x = 10 - 11
100x = -1
x = -0.01
Thus, the value of x is -0.01.

Replace x with 2+i and solve
Remember that i is the square root of -1
My phone automatically capitalizes I, so don’t be confused by that!
y=(2+I)^2 + 3(2+I) +5
y=4+4i-1+6+3i+5
y=7i+14
