D
Step-by-step explanation:
z-m=z+bx
z-m-z=bx
bx=-m
x= - m/b
1/2 * (27 + x) = 19
27 + x = 38
x = 11
b
D. x = 3
- 3 = - 2
First, convert to base 2:
=
Next, convert to base 2:
Apply exponent rule: = :
= * , = *
* - 3 = * - 2
= , =
Rewrite the equation with :
Solve * - 3 = * - 2:
Refine:
Add 3 to both sides:
- 3 + 3 = - 2 + 3
Simplify:
= + 1
Multiply by the Least Common Multiplier (64u):
* 64u = + 1 * 64u
Simplify * 64u:
1024
Substitute:
1024 = + 64u
Solve for u:
u = 8
Substitute back u = :
8 =
Solve for x:
x = 3
C. Parallelogram and rectangle
If it was a square...all the sides would be the same, so it cannot be a square, therefore it is not A or B
