The area of a rectangle is length + length + width + width, or 2l + 2w. Set these equal.
=
+
+ width + width
= 7 + 2w; subtract 7 from both sides
= 2w; divide both sides by 2
= w, or the width (in meters)
7000 is (1/10) of 70,000 - as 7000*10=70,000.
Answer:
The answer to your question is: the second option
Step-by-step explanation:
If two lines are parallel, then their slopes are the same
Slope of the lower line :
m = (-d - 0) / (0 + c)
m = -d / c
Slope of the upper line:
m = ( 0 - a) / (b - 0)
m = - a/ b
finally
-d/c = -a/b
Answer:
22
Step-by-step explanation:
first find the square root of all the sides then add them up and divide by two and your answer should be 22 hope this helps
Answer:
x= 3, x=5 or x^2 + 8x + 15
Step-by-step explanation:
(x+3)(x+5)
(x*x)(x*5)(3*x)(3*5)
x^2 + 5x + 3x + 15
x^2 + 8x + 15
x+3 = 0 x+5 = 0
-3 -3 -5 -5
x= -3 x= -5
