Answer:
the first one
8x+5
Step-by-step explanation:
10x-2-2x+7= 8x+5
To find the magnitude of a vector, take the components, square them, then add them, then take the square root. This is very similar to the Pythagorean Theorem.
For your particular problem, I’ve included a picture showing how that specific calculation is done. :)
- Surface Area of a Cube = 6(L)²
- Surface Area of this cube = 6(3.2)²
= 61.44 m²
Answer:
7(7x -4)
Step-by-step explanation:
49x-28
We can factor a 7 from each term
49x = 7*7x
28 = 7*4
7(7x -4)
Supplementary angle = 180
180 - 51 = x
x = 129
C) 129 degrees is your answer
hope this helps
