A) Antoine's family is taking a summer vacation through the northern united states on day one of the trips the family will be travelling 85 miles on day two of the trip they will travel 125 miles on the third day they will travel 176 miles how many kilometres will Antoine and his family travel each day? (calculate to the nearest kilometres.) b) How many miles and kilometres will they travel in total?

Step-by-step explanation:

We are expected to convert from miles to kilometer

first day 85 miles =136.794km

Second day 125 mile=201.168km

third day 176 miles =283.245km

Total distance covered is

136.794km+201.168km+283.245km=621.207km

Therefore the total distance in kilometer is 621.207km

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
