Use the graphs to estimate both solutions to x^2+x-4=0

Mathematics
1 answer:
Bogdan [553]3 years ago
4 0

Answer:

No graph so we'll use the quadratic formula

x^2+x-4=0

a = 1

b = 1

c = -4

x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2

x = (-1 +- sqr root (1 +16) ) / 2

x1 = (-1 + sqr root (17)) / 2

x2 = (-1 - sqr root (17)) / 2

Step-by-step explanation:

Triangle has sides 7 inches, 7.5 inches, and x inches. What is the range of possible lengths for side x, in inches?
jarptica [38.1K]

Answer:

<em>0.5 < x < 14.5</em>

Step-by-step explanation:

<u>Triangle Inequality Theorem </u>

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining those inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given two of the triangle side lengths as y=7.5 and z=7, thus the third side length (x) can be in the range:

7.5 - 7 < x < 7.5 + 7

0.5 < x < 14.5

<u>Note: The latter is the correct answer but none of the choices is accurate. Choice D is closer to the correct answer but the endpoints cannot be included.</u>
