Barry uses the expression " square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared " to find the distance between point E(3, 1) and point F(4, 7).
Step-by-step explanation:
Given : Barry is trying to calculate the distance between point E(3, 1) and point F(4, 7).
Distance between two points can be calculate using distance formula,
Distance formula states given two points P(a,b) and Q(c,d) the distance between P and Q can be calculated using the given expression ,
Thus, distance between point E(3, 1) and point F(4, 7) can be calculate using above formula as ,
Here, a= 3 , b= 1 , c = 4 and d = 7
Substitute above values, we get,
Thus, Barry uses the expression " square root of the quantity of 7 minus 1 all squared plus 4 minus 3 all squared " to find the distance between point E(3, 1) and point F(4, 7).
Thus, Option (1) is correct.
