Just plug in a = 5, y = -3 in that!
2a + ay = 2(5) + 5(-3) = 10 -15 = -5
thats it!
Answer:
The area of square is 64ft².
Step-by-step explanation:

Answer:
360 min
Step-by-step explanation:
Given
3 miles ---> takes 30 minutes
1 miles ----> takes 30/3 = 10 minutes
36 miles ----> takes 10 x 36 minutes = 360 minutes
X² + 10x +2 = 0 .Complete the square of (x² + 10x + ??)
We know that (10x) is equal to twice the square root of the 1st (x) by ??
10x = 2.x.(??) and ?? = 5 and its square is 25. Then I have to add 25 and subtract 25 so that not to change the equation:
(x² + 10x + 25) -25 +2 =0
(x+5)² -23
