Answer:
43
Step-by-step explanation:
3x + 10 = 5x - 12
10 = 2x - 12
22 = 2x
x = 11
check:
33 + 10 = 55 - 12
43 = 43
correct
x = 11 so bring this into 3x + 10
we get 43
You could just factor out the Trinomial and find the zeros of the equation,
x^2 - 2x -15 = (x - 5)(x + 3) = 0,
x - 5 = 0 and x + 3 = 0, so x = 5,-3 AKA answer choice C
Answer: 300a^3cb
Step-by-step explanation:

Answer:
=537.6 acres
Step-by-step explanation:
1 acre = 43560 ft^2
5280ft = 1 mile
Area of the farm
0.6miles×1.2miles = 3168ft×6336ft
=23,417,856ft^2
=23,417,856÷43560
=537.6 acres
27. You can do this by thinking of all the pairs that add up to 9( 1 and 8, 2 and 7, 3 and 6, 4 and 5) and arrange them to get numbers.
