<h3>
<u>The value of the number is equal to 11.</u></h3>
2x - 9 = 13
<em><u>Add 9 to both sides.</u></em>
2x = 22
<em><u>Divide both sides by 2.</u></em>
x = 11
Try 135. I’m not foresee!
43 and 5/6 because 12 and 1/4*2 is 24 and 1/2 then 9 and 2/3*2 is 19 and 1/3 and when you add that you get 43 and 5/6
If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
