2x^2 + 60x + 400

If you multiply the first two equations to find the total area of the garden, then you can subtract the size of the path from tha and then you'll have your answer.... Math is the best thing ever

Answer:

2x^2+60x+400

Step-by-step explanation:

First we have to find the total area of the garden then:

(3x+30)(x+20)=3x^2+60x+30x+20=3x^2+90x+600

Now we just have to substract the walkway area tha is x^2+30+200 then:

3x^2+90x+600-(x^2+30x+200)=3x^2+90x+600-x^2-30x-200)=

2x^2+60x+400

Keith left his house, rode his bike 3 miles along one road, took a 90 degree turn, and rode 3 miles to the local swimming pool.

For this case we can model the problem as a rectangle triangle.
 We know:
 Length of the sides of the triangle
 We want to know:
 Length of the hypotenuse
 Using the Pythagorean theorem we have:
 d =  \sqrt{3^2 + 3^2}
 Rewriting the expression we have:
 d = \sqrt{2(3^2)}
 d = 3\sqrt{2}
 d = 4.2 miles
 Then, the distance that he would have saved if he travels directly is:
 3 + 3 - 4.2 = 1.8 miles

 Answer:
 
he would have saved:
 
1.8 miles

The formula for the surface area of a cylinder is A=2πr(r+h).Find h if A=80π and r=5.
lesya [120]
A=2<span>πr(r+h)
</span>80π=<span>2π(5)(5+h)
</span>80π=10π(5+h)
80π=50π + 10πh
30π=10πh
