Answer:
Let the sides be a and b
a^2 + b^2 = c^2 = 29^2 = 841
a^2 + (a + 1)^2 = 841
a^2 + a^2 + 2 a + 1 = 841
2 a^2 + 2 a = 840
a (a + 1) = 420
21 * 20 = 420 trial and error
So the sides are 20 and 21
20^2 + 21^2 = 29^2
Profit=4 lemons
Sp=20 lemons
Now,
Profit=SP-CP
4 =20-CP
CP=16 lemons
Again
Profit%=Profit/CP ×100 %
=4/16 × 100%
=25%
y=-3/4x+5.5
Step-by-step explanation:
plus and minus
example : 3 ± 5 = 8 or -2
