Answer:
(x²-2x)/(2x+6)
Step-by-step explanation:
When you are asked to divide two fractions just do keep-change-flip. Keep the first fraction, change the ÷ to x and flip the second fraction upside down. So the problem becomes ((x-2)/(x+3)) times (x/2). Then just multiply numerators and multiply denominators.
Answer:
Area of the rectangular trench = 1 square meter
Step-by-step explanation:
length of the garden = 2 1/2 m width of the garden = 2 m
length of both garden and trench = 3 1/2 m
width of both garden and trench = 3m
Length of the trench = Difference in length
= 3 1/2 m - 2 1/2 m
= 7/2 - 5/2
= (7 - 5) / 2
= 2/2
= 1 m
Length of the trench = 1 m
Width of the trench = difference in width
= 3 m - 2 m
= 1 m
Width of the trench = 1 m
Area of the rectangular trench = length × width
= 1 m × 1 m
= 1 m²
Or
1 square meter
Area of the rectangular trench = 1 square meter
Answer: What's the question?
Step-by-step explanation:
This parabola is looking up, so it can be C. or D.
We can take a point like vertex (-2, -3) and check it.
<span>
D. y=x² + 4x + 1
</span>-3 =(-2)² + 4(-2)+1
-3 = 4 - 8 +1
-3 = -3 True.
C. <span>y=2x² + 4x + 1
</span> -3 = 2(-2)² +4(-2)+ 1
-3= 8 -8+1
-3 = 1 False
So, correct answer is D. y=x² + 4x + 1
