A^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 137^2 - 105^2
b^2 = 18769 - 11025
b^2 = 7744
b = sqrt 7744
b = 88
Gina's step is not correct... the length of the unknown leg is not 7744, it is the sqrt of 7744, which is 88
'karen is making 14 different kinds of greeting cards she is making 12 of each kind how many greeting cards does she making'
ok so that is multiplication
14 times 12 since it is 12 of each and 14 of them so
14 times 12=
do you guys still do multiplication by the tower meathod or such if so, here it is
14
<span><u>12 x</u>
</span>
so it is
if you had
a b
<u>c</u><span><u> d x</u></span>
(ad)(bd)
<u>(bc)(ac) +</u>
result
first you do
2 times 4 then place it below the 2
14
<span><u>12 x</u>
</span> 8
then you do 2 times 1 then place it below
14
<span><u>12 x</u>
</span>28
then you move on the the one
1 times 4
14
<span><span><u>12 x</u>
</span>28
4
then 1 times 1<span>
</span></span> 14
<span><span> <u>12 x</u>
</span> 28
14
</span>
then we add
14
<span><span> <u>12 x</u>
</span> 28
<u>14 +</u></span>
