Answer:
a = x² + 3x - 40
Step-by-step explanation:
a = l * w
a = (x - 5)(x + 8)
a = x(x + 8) - 5(x + 8)
a = (x² + 8x) + (- 5x - 40)
a = x² + 3x - 40
I would try Khan Academy. He does very good explainations
<span>y = 50x/(x+33)
x≠-33
xy + 33y = 50x
33y = x(50-y)
33y/(50-y)= x
or y≠50
=> yϵ R - {50} </span>
Answer:
A is the answer
Step-by-step explanation:
What you do is you cross multiply 24x4 which equals 96. Then, you divide by 16. Which gives us: m = 6
B. 21.39 because I said so and I did all the calculations and apparently I need more than 20 words but there is your answer enjoy
