Answer:
width: 13 Length: 15
Step-by-step explanation:
Let length be x
width is x-2
perimeter is 56
P= 2(l+b)
56= 2(x +x-2)
56/2 = 2x - 2
28 + 2 =2x
30= 2x
15 =x
15-2+13
length =15
width = 13
Answer:
x +10 =0 (1)
-8x -9y=1 (2)
x=-10 => (2) 80-9y=1 =>y=9
=> x=-10, y=9

Step-by-step explanation:
1.20 x 18=21.6 Therefore 3/7 is equal to $21.6. So 21.6/3= 7.2 which is equal to 1/7. If 7.2 is 1/7 that means that 7.2 x 7 which is 50.4 is your answer. So she had $50 and 40 cents. PLEASE MARK BRAINLIEST ANSWER :)
The stone takes 4sec to reach the water level.
initial velocity (u)=0
time(t)=4s
acceleration due to gravity(a)=
9.8(10 approx)
so,its final velocity will be
v=u+at
0+10×4=40
v=40m/s
