Answer:
152 cm
Step-by-step explanation:
Once again its a square. All sides are equal.
Square root 361 to get 19.
19 x 19 = 361
4 was sewed together.
You could either add, 361+361+361+361
Or you could multiply, 361 x 4
Either way you get 1444.
You could either square root 1444 to get the side length or you could add the previous side length to itself once to get the new side length of 38.
Now you need to get perimeter.
P=4 x length
P=4 x 38
152 cm
Answer:
r+7
Step-by-step explanation:
Let b be the speed of the boat, and c be the speed of the current. Then:
20/b+c=2/3 hr
20/b-c=1 hr
2/3b+2/3c=20
b-c=20
Then:
b+c=30
b-c=20
2b=50
b=25 mph
c=5 mph
