Answer:
B : Length is 12, Width is 9
D: Area is 108
Step-by-step explanation:
Finding x:
Since the Perimeter is 42, subtract 14 from 42 to get 28. Then divide that by 4 to get 7. x = 7. Since x = 7 then 7 + 5 = 12. So the length is 12.
Figuring out the width:
When we find the perimeter we add all the sides, so 12 + 12 = 24 and 42 - 24 = 18. Divide 18 by 2 to get 9 and then add 12 + 12 + 9 + 9 just to check your answer
Since the you know the legnht and width, you now have to multiply them to fine the area. 12 x 9 = 108
Step-by-step explanation:
-2x² + 5x - 3 - (-7 - 9x + 5x²)
= -2x² + 5x - 3 + 7 + 9x - 5x²
= -7x² + 14x + 4.
Hence the coefficient of the x term is 14.
