2 x length + 2 x width = perimeter.
2(2s-5) + 2(4s-13) = 108
Simplify:
4s-10 + 8s-26 = 108
Combine like terms:
12s - 36 = 108
Add 36 to both sides:
12s = 144
Divide both sides by 12:
s = 144/12
s = 12
Now replace s with 12 in each equation:
2(12) - 5 = 24-5 = 19
4(12) - 13 = 48-13 = 35
The answer is d. 35,35, 19,19
Answer:47.14km/h
Step-by-step explanation:
585÷3 and 1/2=167.14km/h
70÷35/60=120km/h
167.14-120=47.14km/h
-6 it is just the opposite of the number. So a positive would be a negative and a negative a positive. So the answer to your question is -6.
Answer:
Median = 45
Step-by-step explanation:
Since the given data set is already in ascending order, we we just have to find the middle most number of the data set:
There are 2 middle numbers 40 and 50, so to find the middle most number find their average:
(40 + 50) / 2 = 45
Median = 45
Hope this helps!
Answer:
c = 9/16
Step-by-step explanation:
<h3>step1</h3>
(a-b)²
a² - 2ab + b²
here a = x
b = ?
so
x² - (2)(x)(?) + ?²
Now we can see that -(2x)? = -3x/2
-2x? = -3x/2
cancel -x on both sides
2? = 3/2
? = 3/2 * (2)
? = 3/4
so b = 3/4
<h3>step2</h3>
(x² - 3x + 9/16) = (x-3/4)²
so from the expression we can see that C = 9/16
