answer
-8>0
step by step
-8:--------. NB you owe something or someone
0: you don't have anything or you don't owe anything
Answer:
substitute the given values for m, n, and p into each problem and solve. Make sure you don't ignore minuses and negatives. Separate with parentheses to make sure you don't get confused.
Step-by-step explanation:
54: -7(-5) - 10( 3/2)
35 - 10(1.5)
35 - 15
20
55. -3mnp
-3 x (-5) x 3/2 x (-8)
15 x 1.5 x (-8)
22.5 x (-8)
-180
56. 8n / (-6p)
8(1.5) / (-6 x -8)
12 / 48
1/4 or .25
57. p squared is (-8)(-8)
2(-8)(-8)(-1.5) / (-5)
128 (-1.5) / (-5)
-192/ (-5) negatives cancel out
192/5

Answer:
D)4x + 6/(x + 1)(x - 1)
Step-by-step explanation:
A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle
where
is the perimeter
is the length
is the width
We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so and .
Replacing values:
Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula where is the first term and is the second term. We can infer that and . So, . Replacing that:
We can see that the common denominator of our fractions is . Now we can simplify our fraction using the common denominator:
We can conclude that the perimeter of the field is D)4x + 6/(x + 1)(x - 1).
Answer:
Triangles PRQ and MRN are not similar.
Step-by-step explanation:
The two triangles are PRQ and MRN.
It is given that both the triangles have ∠R = 90° as the common angle.
Now, we check whether the ratios of the sides are equal or not.
i.e. To check if
Since, we have the lengths,
PM = 8, MR = 10. Thus, PR = 8 + 10 = 18
QN = 14, NR = 7. Thus, QR = 14 + 7 = 21
So, we get,
implies
implies 1.8 = 3, which is not true.
So, the ratio of the sides are not equal.
Hence, we get that the triangle PRQ and MRN are not similar.
