The lawn area of uniform width can be written as follows:
A = (40 + 2x) * (35 + 2x) - (40) * (35)
Where,
x: width of the lawn
Substituting the value of the area we have:
316 = (40 + 2x) * (35 + 2x) - (40) * (35)
Rewriting:
316 = 1400 + 80x + 70x + 4x ^ 2 - 1400
Rewriting we have:
4x ^ 2 + 150x - 316 = 0
Solving the polynomial we have:
x1 = - 79/2
x2 = 2
Taking the positive root we have that the grass width des:
x = 2 yards
Answer:
The width of the lawn that surrounds the garden is:
x = 2 yards

Answer:

Step-by-step explanation:
The trick here is to know the distance formula (a formula that helps you find the distance between two points).
Distance formula: distance = 
But now that we know this, we can simply plug in our values and solve!

Now we can tell from our answer that the distance between both points is 
Answer:
your answer is 7 because 9 times 2 = 18 then + 7 = 25

Step-by-step explanation:
<u>If the triangles are similar that means the ratio of the sides of the triangles are the same.</u>
Sense the left side of bigger triangle is 4 times bigger than the bottom side of the triangle, then the left side of the smaller triangle is 4 times bigger than the bottom side.
