Answer:
I'm not sure if you mean the type of triangle or the other number but I'm pretty sure it's an equilateral triangle and the the number is 8.
Step-by-step explanation:
Let the two numbers be -x and -x - 1, then
-x(-x - 1) = 1,122
x^2 + x = 1,122
x^2 + x + 1/4 = 1,122 + 1/4
(x + 1/2)^2 = 4,489/4
x + 1/2 = sqrt(4,489/4) = + or -67/2
x = 67/2 - 1/2 = 66/2 = 33
Therefore, the two numbers are -33 and -34
The simplest way to find percent is to take the partial number, divide by the whole number, and multiply the answer by 100%.
= 0.4
0.4 x 100% = 40%.
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:
10
Step-by-step explanation:
a^2 + b^2 = c^2
6^2 + 8^2 = c^2
36+64 = square root of 100
square root of 100 is 10
