Answer:
Step-by-step explanation:
(2n - 3)(5n + 6) = 2n*(5n + 6) -3*(5n +6)
=2n*5n + 2n*6 -3*5n + (-3)*6
=10n² + 12n - 15n - 18
= 10n² -3n - 18
Answer:
Solving mathematics isn't as difficult as we think.All you have to do is follow the steps and practice more questions
practice makes perfection
The answer is 44 because all you have to do is use PEMDAS to solve the equation
2.5 (2 hours and 30 mins) hours. Distance (6.8) divided by time (2.72). 6.8/2.72= 2.5
If you work backwards, she had 24 before going to the movies. This is 3/5 of what she had originally. Use this to find 1/5 the but dividing 24 by 4 = 8 then multiply by 5 to get back to the original value 8 x 5 = 40
