Step-by-step explanation:
You would have to find out how many square feet the lawn is first:
70 x 50 = 3500 square feet
You are told that one pound = 200 square feet so use this to calculate how many pound you’ll need for 3500 square feet.
3500 square feet divided by 200 square feet = 17.5 pounds

Answer:
y=4x+3.....hope this helps ; )
Step-by-step explanation:
18+3x=-10+x
3x-x=-10-18
2x=-28
x=-14
Given:
right triangle
a = 2.9
c = 4.2
Pythagorean Theorem: a² + b² = c²
missing value of b.
b² = c² - a²
b² = (4.2)² - (2.9)²
b² = 17.64 - 8.41
b² = 9.23
b = √9.23
b = 3.03 or 3.0
The value of b is 3.0
