Answer:
25.2X + 3.4 centimeters.
Step-by-step explanation:
The formula for the perimeter of a rectangle
= 2L + 2W
= 2(L + W)
From the question:
Width of a rectangle (W) = 9.7 X - 4.7 centimeters
Length of a rectangle (L) = 2.9 X + 6.4 centimeters
Imputing it into the formula
2(L + W)
2( 9.7X - 4.7 + 2.9X + 6.4)
2 (9.7X + 2.9X - 4.7 + 6.4)
2( 12.6X + 1.7)
= 25.2X + 3.4 centimeters.
Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.
Answer:
x = 40
Step-by-step explanation:
In order for m and n to be parallel, the corresponding angles need to be equal. Therefore we get the equation:
3x = 120
Divide both sides by 3 to get:
x = 40
Answer:
13
Step-by-step explanation:
x+5=3x+2
5=2x+2
3=2x
x=1.5
1.5+5=6.5
6.5 is half of DF, DF=13
Answer:
Step-by-step explanation:
We have been given that in a recent year, 304 of the approximately 300,000,000 people in the United States were struck by lightning.
Therefore, the probability that a randomly selected person in the United States will be struck by lightning this year is .
