Answer:
7
Step-by-step explanation:
A rectangle has a length that is 8 times the width
The area of the park is 392 square units
Let y represent the width of the park
Since the length is 8 times the width then, l= 8x
Therefore the width of the park can be calculated as follows
8x × x= 392
8x^2= 392
x^2= 392/8
x^2= 49
x= 7
Hence the width of the park is 7
Answer:
25x³ + 13x² + 12x + 3
Step-by-step explanation:
(3x²+ 5x +6) + (25x³ + 10x² + 7x– 3)
3x²+ 5x + 6 + 25x³+ 10x² + 7x – 3
25x³ + 3x² + 10x² + 5x + 7x + 6 - 3
25x³ + 13x² + 12x + 3
Step-by-step explanation:
okay so -25 • -9 = 9+10
225 = 9+10
225 = 19
19. 19
= 11.8
