Pretty sure 200feet but its kinda easy
Answer:
i’m pretty sure it’s because they make 180°
Step-by-step explanation:
<span>So we have a polynomial 5x^5-9x^3+2x^11+6 and we are wondering what is its degree, leading coefficient, number term and the constant term. The degree of a polynomial is its highest power so here that is 11. Leading coefficient is the term with the highest degree of a polynomial and here thats 2. Number of terms is 4 because that many numbers are in this polynomial and the constant term is 6 beccause it is a constant. </span>
Step-by-step answer:
Given:
A triangle
Perimeter = 60 cm
longest side = 4* shortest side (x)
Solution:
longest side = 4x
shortest side = x
third (intermediate side = 60 -x -4x = 60-5x
The triangle inequality specifies that the sum of the two shorter sides must be greater than the longest side to form a triangle. Hence
x + y > 4x
x + 60-5x > 4x
60 - 4x > 4x
8x < 60
x < 60/8 = 7.5, or
x < 7.5
Therefore to form a triangle, x (shortest side) must be less than 7.5 cm.
Examine the options: both 7 and 5 are both less than 7.5 cm.
40, 30 and 25 all have a problem because the longest side (4 times longer) will exceed the perimeter of 60.
Now also examine cases where 4x is NOT the longest side, in which case we need
4x>=y
or
4x >= 60-5x
9x >=60
x >= 6.67
so x=5 will not qualify, because 4x will no longer be the longest side.
The only valid option is x=7 cm
The side lengths for x=7 and x=5 are, respectively,
(7, 25, 28)
5, 20, 35 (in which case, the longest side is no longer 4x=20, so eliminated)
