X^2=24
Root both sides
x=±√24
Simplify the radical
x=± √2^2 *6
x=± 2√6
Final answer: A
Answer:
4.1 -
300/22= 13.65
so the answer is 13.63
4.2
distance/speed
330/110= 3
So it'll take 3 hours
4.3
sorry not sure for this one :(
Answer:
Step-by-step explanation:
In 
begin by multiplying both sides by a to get
rs = ak and divide away the s to get
Answer:
1. 5/4
2. 7
Step-by-step explanation:
1) Lets call the width as w
Therefore length would be:
w+4
To find the perimeter you use the formula:
2 (l+w)
Now substitute our values into this formula:
2 (w+4+w)
2( 2w+4)
4w+8
Now make this equal to 13:
4w +8 = 13
4w = 5
w = 5/4
2. In this question we will call length l
Therefore width would be:
l-5
Now we will do the steps we did above:
2 (l+l-5)
2 (2l-5)
4l -10
4l - 10 = 18
4l = 28
l = 7
Answer:
X= -12
Step-by-step explanation:
-2x-4=20
-2x-4+4=20+4
-2x=24
x=-12
