Answer:
Step-by-step explanation:
Use the identity:-
a^2 + b^2 = (a + b)^2 - 2ab
Plugging in the given values;-
a^2 + b^2 = 6^2 - 2*7 = 36-14 = 22 Answer
To be honest I really don’t know sorry for not helping
Y = kx√z where k is some constant
To find the value of k we plug in the given values of x,y and z:-
6 = k*3*√9
6 = k*3*3
9k = 6
k = 6/9 = 2/3
so the relation is y = (2/3)x√z
When x = 4 and √z = 3.6 we have:-
y = (2/3)*4 * 3.6
= 9.6 Answer
