It is not a square, square has equal sides.
Using Pythagoras Theorem
a^2+b^2=c^2
(1.2)^2+(2.3)^2= c^2
c^2= 6.73
c= 2.594224354214569 (Negative value rejected, length cannot be negative)
Therefore the diagonal should be longer.
Hope it helps :)
Answer:
"Mikes repair shop $100 service charge plus $65 per hour Amys auto repair $40 service charge plus $80 per hour write an equation for each repair shop to represent the total cost of a car repair as a function of the number of hours worked let C = total cost to you let h = number of hours worked. Suppose you need to get the dent in your car repaired you see the ads above in the newspaper your father who knows a bit about cars said it would take no more than 3 hours for the repair person to fix your car how do you determine where you should take your car to get it repaired
-Mike Cost:: M(3) = 100 +65*3 = $295
-Amy Cost:: A(3) = 40 + 80*3 = $280
------------------------------------------------------------
-Mike charges 100 dollars service charge plus 65 dollars per hour.
-Amy charges 40 dollars service charge plus 80 dollars per hour.
-The cost to repair from mike is 100 + 65 * x.
-The cost to repair from amy is 40 + 80 * x.
------------------------------------------------------------
Let x = 3 and you get:
The cost to repair from mike is 100 + 65 * 3 = 295 dollars.
The cost to repaid from amy is 40 + 80 * 3 = 280 dollars.
As long as the time to repair is 3 hours or less, the cost to repair will be cheaper from Amy."

Answer:
Step-by-step explanation:
To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5. Therefore, the slope of every line parallel to this line would have to be m = 4/5. Two lines are perpendicular if
3/5 is greater than 1/4 and if u dont trust me then look at a graph
Filling in y=1+i without the missing term yields -3-4i.
-3-4i = -3(1+i) - i
So we have to add 3(1+i) to get to -i.
3(1+i) = 3y, so 3y is the answer.
