<span>Let x be length of shorter leg
</span>4cm longer than the shorter leg<span> x + 4 = length of longer leg
</span>hypotenuse is 8 cm longer than the shorter <span>
x + 8 = </span>length of <span> hypotenuse
</span>
phytagorus rule
<span>x^2 + (x+4)^2 = (x+8)^2
x^2 + x^2 +8 x + 4^2 = x^2 + 16x + 8^2
x^2 - 8x - 48 =0
(x + 4 ) (x - 12) - 0
x= - 4 we reject negative number
so x= 12

360 degrees in a circle divided by 5 is 72
"y = -0.6x + 346" is the one equation among the choices given in the question that <span>represents the depth of the lake, y, based on the number of weeks passed, x. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has helped you.</span>
He owns his mother $0; Because $21.50 - $21.50 is Zero
You would subtract the 1 first and leave the number with the X alone. Then after you have subtracted the 1 you would want to divide the 2x by 2 and also divide the 8 by 2
