Answer:
x>4
Step-by-step explanation:
Sorry if there is any mistakes
Because the movement of the minute han of a clock is clockwise ↓, then the angle of rotation will be negative.
1) we calculate the number of minutes from 6:10 to 7:00
number of minutes=7:00-6:10=6:60 - 6:10=50 minutes.
2)
We know that:
60 minutes of a clock have turned -360º
Then:
60 minutes of a clock------------------------- -360º
50 minutes of a clock------------------------- x
x=(50 minutes of a clock * (-360º))/60 minutes of a clock=-300º
Answer: A. -300º
The time periods from oldest to youngest:
Silurian
Triassic
Jurassic
<span>Tertiary</span>
x+y = 652
x-3y=0
need to enter those into a graphing calculator to get the answers
x=489 ( games)
y=163 ( system)
them check 163*3 = 489 and 489+163 = 652
Answer:
(x+11)(x-11)
Step-by-step explanation:
Hello!
We are given the expression x²-121, and we want to factor it
The expression is a difference of squares expression.
The formula for the difference of squares is written as a²-b² can be factored as (a-b)(a+b)
121 is 11 squared, and x² is x squared
So that means that a=x, and b=11 in this case
Now substitute those values into the formula
a²-b²=x²-121=<u>(x+11)(x-11)</u>
Hope this helps!
