Answer:
The complete length is 115 cm.
Step-by-step explanation:
Given:
If 20%of a length is 23 cm.
Now, to find the complete length.
Let, the complete length be .
So, according to question:
20% of = 23 cm
Dividing both sides by 0.20 we get :
Therefore, the complete length is 115 cm.
Answer:
33.44 cm²
Step-by-step explanation:
sorry if incorrect
Answer:
The point ( 0,-1) is a solution.
Step-by-step explanation:
y<= (x+1) (x+5)
y>= (x-1)^2 -6
See attached graph.
To prove algebraically, put the point (0,-1) into both equations and see if it is true for both of them.
y<= (x+1) (x+5)
-1 <= (0+1) (0+5)
-1<= 1*5
-1 <=5
True
y>= (x-1)^2 -6
-1 >= (-1)^2 -6
-1 >= 1-6
-1 >=-5
True
The point is a solution
The answer is C. The answer is C because it’s like subtracting. 6-3 equals 3
You would do 50+25-45. That would equal 30 points.
