Answer:
The length of the rectangle = 63 ft
Step-by-step explanation:
Let us assume the width of the rectangle = m ft
So, the length of the rectangle = 3 x Width = 3 x m = 3 m ft
Perimeter = 168 ft
PERIMETER OF A RECTANGLE = 2 (LENGTH + WIDTH)
⇒ 168 ft = 2 ( 3 m + m)
or, 168 = 2 ( 4 m)
or, 8 m = 168
⇒ m = 168/8 = 21
or, m = 21 ft
Hence, the width of the rectangle = m = 21 ft
And the length of the rectangle = 3 x m = 3 x 21 = 63 ft
1. 0.3z-13-4z+6.7
0.3-4z=-3.7z
-13+6.7=-6.3
simplified- -3.7z-6.3
2. 3x+1+6x-2+3x+1+6x-2= 18x-2
3. don’t know this one
4. 5(t-1.25) = 8.75
5t-6.25=8.75
5t=8.75+6.25
5t=15.00
t=3
Answer:
(x - 9)(x + 2)
Step-by-step explanation:
x² - 7x - 18
x² + 2x - 9x - 18
x(x + 2) - 9(x + 2)
(x - 9)(x + 2)
