The first equation can be simplified down to 3 and -\frac{3}{2}[/tex]. Therefore, ">" is correct.
The second equation can be simplified down to 12 and 6.25. Therefore, "<" is incorrect. It should be ">".
Answer:
61
Step-by-step explanation:
84+38=122
180-122=58
DBC=58
180-58=122
122÷2=61
61+58=119
180-119=61
Answer:
L₄₂ = 83.4
Step-by-step explanation:
Put 42 where n is and do the arithmetic.
... L₄₂ = 75 + 0.2·42
... = 75 + 8.4
... = 83.4
Let the width be "x" cm.
Then the length is "x+12" cm
And the area = x(x+12) = x^2+12x cm^2
----------------------------
Change the dimensions:
width = "x-2" cm
length = "x+10" cm
New area = (x-2)(x+10) = x^2 + 8x - 20 cm^2
------------------
Equations :
Old area - New area = 108 cm^2
x^2+12x -(x^2 + 8x - 20) = 108
4x + 20 = 108
4x = 88
x = 22 cm (original width)
x+12 = 24 cm (original length)
