A triangle has one side length of 12 inches and another of 8 inches. Describe all possible lengths of the third side.
jasenka [17]

Answer:

The possible lengths of the third side is all real numbers greater than 4 inches and less than 20 inches

Step-by-step explanation:

we know that

<u>The Triangle Inequality Theorem</u>. states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

Let

x -----> the possible lengths of the third side

Applying the Inequality Theorem

1) 12+8 > x

20 > x

Rewrite

x < 20 in

2) 8+x > 12

x> 12-8

x > 4 in

therefore

4 in < x < 20 in

The possible lengths of the third side is all real numbers greater than 4 inches and less than 20 inches

Evaluate the function f(x)=4x^2-10+2 find f(-7)
likoan [24]

Answer:

188

Step-by-step explanation:

f(x)=4x² - 10+2

f(-7) = 4x² - 10 + 2

= 4(-7)² - 10 + 2

= 4 (49) - 10 + 2

= 196 - 10 + 2

= 188
