Two sides of an acute triangle measure 5 inches and 8 inches. The length of the longest side is unknown.
nordsb [41]

The greatest whole possible whole number length of the unknown side is 9 inches

<em><u>Solution:</u></em>

Two sides of an acute triangle measure 5 inches and 8 inches

The length of the longest side is unknown

We have to find the length of unknown side

The longest side of any triangle is a hypotenuse

<em><u>For a acute triangle we know:</u></em>

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

c^2

Here in this sum,

a = 5 inches

b = 8 inches

c = ?

Substituting we get,

c^2< 5^2+8^2\\\\c^2 < 25 + 64\\\\c^2 < 89\\\\c < 9.4

On rounding to nearest whole number,

c < 9

Hence, to the greatest whole possible whole number length of the unknown side is 9 inches

photoshop1234 [79]

Answer:

$3.25 per gallon

Step-by-step explanation:

She had $30 and now has $4, so she spent $30- $4 = $26

With $24 she bought 8 gallons of gas.  

$26/(8 gallons) = $3.25/(1 gallon)      [ divide 26 by 8 to get the unit rate]

She spent $3.25 per gallon

Answer:

Explanation:

7. f(x) = x^4 + 3x^3 - 6x^2 - 10x + 8
f(2) = 2^4 + 2^3 - 6^2 - 10(2) + 8
f(2) = 16 + 8 - 12 - 20 + 8
f(2) = 0

8. x^2 - 9 = (x - 3)(x + 3)
x ^2 + x - 6 = (x + 3)(x -2)

Thus, the common factor is x + 3
