Answer:
Hello! answer: 13
Step-by-step explanation:
-4 × 13 = 52 therefore a = 13 HOPE THAT HELPS!

which means the parabola lies above the x-axis over its entire domain. This means the area is given by
The given scale for the map means that a distance of 1 cm between two locations on the map corresponds to a real distance between them of 600,000 cm = 6 km.
So, if the distance between two places in reality is 87 km, on the map this would be represented by a distance of 14.5 cm, since
87 = 84 + 3
87 = 6 • 14 + 6 • (1/2)
87 = 6 • (14 + 1/2)
To solve the problem, do the problem in the parenthesis () then do your answer with the numbers outside the ().
(8-3) = 5 x 3 = 15
(6 + 4) = 10 / 2 = 5
(6 - 4) = 2 / 2 = 1
(6 x 4) = 24 / 2 = 3
Um... part of the (6 4) doesn't make sense... What goes between the numbers? Plus, minus, multiply or division sign? Please tell.
But, I already got you started off and I'll let you figure out the rest. (If you can not figure out the rest, please tell me what sign is between the 6 and 4 in (6 4) and then I'll give you the answer and a better explanation.)
I hope this helps! :D
