<span>Here the given equation is :
2-8x= -6
By bring -6 on the Left Hand size and taking 8x on the Right Hand side, the equation become.
2+6= 8X
8= 8X
X=8/8
X=1
Hence value of X is 1.
Hence correct option is A.</span>
13x + 7x - 4x = -40
combine like terms o0n the left
16x = -40
divide both sides by 16
x = -5/2 or -2.5
Cot x = cos x / sin x
cot π/4 = cot 45° = cos 45° / sin 45°
We know that sin 45° and sin 45° have the same value:
cos 45° = sin 45° = √2 / 2;
cos 45° / sin 45° = √2/2 : √2/2 = 1
Answer:
cot π/4 = 1
Answer:
Step-by-step explanation:
A tree diagram? I don't think so. Probably it would take a year's supply of paper to record all the possibilities. The question really is do you allow duplications and is 0 allowed to be the first digit.
I would think that both are fine.
So the total number for this number would be 10^9. There probably some sort of algorithm to reduce the number and to check if it is a legitimate choice for this number.
Answer:
Perimeter: 6x+8
Area: 2x²+8x
Step-by-step explanation:
Perimeter- the sum of all sides
So, you do x+4+x+4+2x+2x
Simplify that to- 2x+2x+2x+8
And also simplify that to- 6x+8
Area- length*width
So, it's (x+4)*2x
which is 2x²+8x
