The Varners live on a corner lot. Often children cut across their lot to scar walking distance. The diagram to the right represe

About 12.56 units.
Solve for x by plugging in values into Pythagorean theorem.
$a^{2} +b^{2} = c^{2}$
$x^{2} +(x+12)^{2} = 34^{2}$
Simplify
$2x^{2} + 24x+144 = 1156$
Subtract 144 from both sides
$2x^{2} + 24x = 1012$
divide both sides by 2
$x^{2} + 12x = 506$
complete the square
$x^{2} + 12x + 36 = 506 +36 . = (x+6)^2 = 542$
take the square root of both sides.
$x+6 = 23.28$
subtract by 6 to get about 17.28 for x.
Plug in values for x to get distance traveled on outside of the yard.
17.28 + (17.28 +12) = 46.56
subtract 34 from the length to get the difference in travel. 46.56-34=12.56

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

Leviafan [203]

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textbf{Since it's a right angled Triangle we can } \\ \textbf{ use Pythagoras theorem }$

$\sf{Cos (29°) = \dfrac{b}{c}}$

$\sf{Cos (29°) = \dfrac{b}{260}}$

$\sf{b= 260\cdot Cos (29°) }$

$\sf{b= 260\cdot 0.875 }$

[ $\textsf{Cos(29°)= 0.875}$ ]

$\sf{b= 227.5 in }$

$\textsf{I hope you understood the procedure}$

Stacey had 3 cakes for her party, She had 1/8 of a cake left after the party. How much cake was eaten at her party?

hoa [83]

Answer: 3=24/8 24/8 - 1/8 = 23/8 or 2 7/8

Step-by-step explanation:

Exchange 3 into 24/8 which is still 3 but in 8th’s. Then subtract 1/8 from 24/8 which is 23/8 or 2 7/8

What value should be added to the expression to create a perfect square? x^2 - 20x

boyakko [2]

To complete the square:
we take the coefficient ox "x" (which in this problem is -20)
we divide it by 2
square that number
then add it to both sides of the equation

-20 / 2 = -10
-10^2 = 100
then we add 100 to both sides of the equation:
x^2 -20x
x^2 -20x +100 = 100
******************************************************
To get the roots of the equation, we take the square root of both sides:
(x -10) * (x-10) = 10
(x-10) = square root (10)
x-10 = 3.1622776602 
x1 = 13.1622776602 
and don't forget that square root of 10 also equals -3.1622776602 
x2 = 10 - 3.1622776602
x2 = 6.8377223398
