Un triangolo rettangolo isoscele è metà quadrato. L'ipotenusa è la diagonale del quadrato, e i cateti sono i lati del quadrato.
Nei quadrati abbiamo
dove 
è la diagonale e 
è il lato. Usa le informazioni sopra che collegano la diagonale con l'ipotenusa e i cateti con i lati e potrai trovare i cateti, e quindi l'area.
Step-by-step explanation:
12a = 13a - a
12a = 14a - 2a
12a = 15a - 3a
12a = 16a - 4a
12a = 17a - 5a

36 inches is equal to 3 feet ;)

<span>This is the equation made from the problem where x=mystery number
</span><span>2x+3(x+1)=4(x-1)</span><span>
</span><span>Now let's solve for x!
</span><span>
</span><span>We start by distributing 3 into (X+1)
</span><span>
</span><span>3(x)=3x and 3(1)=3
</span><span>
</span><span>Now our equation is 2x+3x+3=4(x-1)
</span><span>
</span><span>Let's combine both x values on the left side of the equation: 2x + 3x=5x
</span><span>
</span><span>We now have 5x+3=4(x-1)
</span><span>
</span><span>Let's distribute 4 into (x-1)
</span><span>
</span><span>4(x)=4x and 4(-1)=-4
</span><span>
</span><span>Now our equation is 5x+3=4x-4
</span><span>
</span><span>subtract 3 form both sides
</span><span>
</span><span>5x=4x-7
</span><span>
</span><span>subtract 4x from both sides
</span><span>
</span><span>x=-7
</span><span>
</span><span>Yay! So the number she is thinking of is -7!</span><span>
