Answer:4/15 of the portion of land is left to be mowed.
Step-by-step explanation:
Portion of Lawn mowed by Mr Strand =2/5
Changing to decimal we have 0.4
Portion of Lawn mowed by his son=1/3
Changing to decimal, we have 0.333
From this , we can deduce that Mr Strand mowed most of the Lawn.
Now to find the portion of Lawn remaining to be mowed
Let total portion be =1whole
Such that portion left to be mowed
=1-(2/5+1/3)
1- 6 + 5/15
1-11/15
15/15 -11/15
4/15 of the portion of land is left to be mowed.

Answer:
x = √17
Step-by-step explanation:
x² = 4² + 1²
x² = 17
x = √17
First take the exponent and 'kill' the 2, by - it from the 3, which gives you just 2x1 (Sorry can't make the one an exponent on this.). Then you take the 2x and times it by itself, so that you end up with 4x. Now you add the 4x and the 5x, to give you 9x. Then -5x from the 9x. to give us 4x again. Now you minus the 2. so that we have 4x-16 dived by x=? from there you dived 4x by 1x to give you 4x. Then you add the -16 over. so that you have 4x=16, then just dived 16 by 4. In the end x=4.
