We first take the absolute value of -7, making 7. This simplifies the equation to 12=w-7. Adding 7 to both sides finds us w=19.
Answer:
Step-by-step explanation:
To find:
The value of 
= ?
Solution:
Kindly consider the equilateral 
as attached in the answer area.
Let the side of triangle = 
units
Let us draw the perpendicular from vertex A to side BC.
It will divide the side BC in two equal parts.
i.e. BD = DC = 
Using Pythagorean Theorem in 
:
Side AD = 
Using Trigonometric ratio:
Putting the values of AD and BD:
Answer: 6 and -6
Step-by-step explanation:
6 Is the distance from zero, since distance cannot be negative, it does not matter if we go left or right on the number line, it will still be 6 units away from zero.
Find the S.A of all the cubes and then add them together.
S.A = 6a²
a is the side length
S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6
Now add them all together.
54 + 24 + 6 = 84
So the total surface area is 84
Hope this helps :)
