No, your written example is in scientific notation
We are asked to prove or disprove the statement : <span>If a divides bc, then a divides b or a divides c. the statement is expressed as a / bc which is equal to a/b * (1/c). The statement is true since a truly is divided by b or a can be divided by c. Or is essential since a is not expressed as a^2 </span>
Answer:
40squared units!
I hope it will be useful.
Step-by-step explanation:
3x+2x+10+2x+5+2x-15 = 360
9x+15-15=360
9x=360
x=40.
- 3x=3×40=120°
- 2x+5=2×40+5=80+5=85°
- 2x+10=2×40+10=80+10=90°
- 2x-15=2×40-15=80-15=65°.
hope this helps you.
