as we move down the list as we push the *digits* to the *left*through the decimal *point* *each* *number has been 10*. and so we can easily *multiply* or divide by *a* power of *10* because of our system of positional numeration. Each Place belongs to the next power of *10*.
Answer:
x = 28
m<ABC = 57°
Step-by-step explanation:
✔️(2x + 1)° + 33° = 90° (complementary angles)
Solve for x
2x + 1 + 33 = 90
Add like terms
2x + 34 = 90
2x = 90 - 34 (subtraction property of equality)
2x = 56
Divide both sides by 2
x = 28
✔️m<ABC = 2x + 1
Plug in the value of x
m<ABC = 2(28) + 1
= 56 + 1
m<ABC = 57°
Answer: 11 units
Step-by-step explanation:
Use the distance formula: 
I believe the answer is :
15x + 40
If you just distribute
Radius 12 units, area = π(12)² = 452.16 unit²
Diameter 16.8 units, area = π(8.4)² = 221.5584 unit²
Radius 3.4 units, area = π(3.4)² = 36.2984 units²
Diameter 10 units, area = π(5)² = 78.5 units²
