Answer:
Blue = 116 m^2
Step-by-step explanation:
The area of the path and the square = 30*30 = 900 m^2
The size of the square = 30 - 2 = 28. The square = 28^2 = 784
The path takes up the difference between the two 900 - 784 = 116
Answer:
One way to factor equation is to find the zeros. Its obvious that x=-1 is solution for this. So one factor is (x+1)
the next factor should include 2x at first (because we have 2x^2 in the equation which can not be made any other way)
Let's suppose the factor is (x+1)(2x+b)
Since we do not know what is b open the brackets 2x^2+bx+2x+b. If this is equal to 2x^2+5x+3 then b=3. We are left with (x+1)(2x+3)=2(x+1)(x+3/2)
Would go for other shorter solutions, but they require some deeper understanding like Horner's scheme,Fermat's Theorem or even deeper which I assume You will not understand)
Answer: 964
Step-by-step explanation:
216/9 = 24
24/6= 4
6+4+9=19
greatest number= 964
Answer:
14 × 23 = 322 this is you answer
The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
