The inequality is in the direction of the arrow
The arrow is like this <——— so the inequality is <
It is an open circle so that means -1 is not included
x<-1
Or choice A
10 * 0.1 = 1
100 drops is 1 fluid ounce.
Answer:
Width = 5
Length = 11
Step-by-step explanation:
Let :
Width, = x
Length = 2x + 1
Area of rectangular garden is given as 55 ft²
Area of a rectangular garden, A = Length * width
Hence,
x * (2x + 1) = 55
2x² + x = 55
2x² + x - 55 = 0
Using the quadratic equation formula :
a = 2 ; b = 1, c = - 55
-b ± sqrt(b² - 4ac) / 2a
Using the quadratic equation solver to save computation time :
The roots are :
-5.5 and 5
Dimension can't be negative ; so x = 5
Hence,
width, x = 5
Length, 2x + 1 = 2(5) + 1 = 10 + 1 = 11
Hence,
Width = 5
Length = 11
Answer:
B. (2d^2 - 3d-21)/((d+2)(d+3))
Step-by-step explanation:
(d^2 - 5d + 6)/(d^2 + d - d) + (d^2 - 4d-5)/(d^2+3d+2)
(d^2 - 5d + 6)/(d^2 + d - d) = (d-3)/(d+3)
(d^2 - 4d-5)/(d^2+3d+2) = (d - 5)/(d+2)
(d-3)/(d+3) + (d - 5)/(d+2)
Least common Multiplier of d + 3 and d + 2 is (d+3)(d+2)
((d-3)(d+2))/((d+3)(d+2)) + ((d-5)(d+3))/((d+2)(d+3))
((d-3)(d+2)+(d-5)(d+3))/((d+3)(d+2))
(2d^2 - 3d - 21)/((d+2)(d+3))
