The steps involved in <span>practical problem solving are as follows:
</span><span>Assign an identifying variable to the quantity to be found.
</span>
<span>Write a sentence stating conditions placed on the quantity.
</span>
<span>Solve the sentence for the variable.</span>
First you put (x+5) into the initial function wherever you see x so it becomes
(x+5)^2+3(x+5)-10=x^2+kx+30
(x^2+5x+25)+(3x+15)-10 simplified left side
x^2+8x+30 fully simplified left side
thus k=8
x^2+8x+30=0 to find 0s
-4 + 3.7416573867739i
<span>-4 - 3.7416573867739i
</span>these are the roots you find after using the quadratic formula
the second one is the smallest

Hi, there!
_____
To find the missing side length of this triangle (which is a <em>right</em> triangle), we'll use Pythagoras' Theorem.
Here,
Hypotenuse (the longest side): c
We know that
So, we can substitute our parameters, and solve for c.
square 2 and 28
add the numbers
square root both sides
Hope the answer - and explanation - made sense,
happy studying!!
"8 in., 15 in., 17 in." is a right triangle and "<span><span>4 in., 15 in., 17 in.</span>" is not a right triangle. Hope this helps!</span>
