Answer:

No, the pool will not fit.

Step-by-step explanation:

Radius of pool: 3.14 r^2= 379.94

Divide by 3.14: r^2= 121

Square root both sides: r=11

11>10, thus the pool won't fit.

3x to the power of 3 + 21x squared + 36x = 0 by factoring the quadratic equation.
Diano4ka-milaya [45]

Answer:

x = 0, -4 and -3.

Step-by-step explanation:

The given expression is "3x to the power of 3 + 21x squared + 36x = 0".

We can write this expression as follows :

3x^3+21x^2+36x=0

Taking 3x common.

3x(x^2+7x+12)=0\\\\3x=0\ \text{and}\ (x^2+7x+12)=0

x = 3

x^2+7x+12=0\\\\x^2+3x+4x+12=0\\\\x(x+3)+4(x+3)=0\\\\(x+4)(x+3)=0\\\\x=-4,-3

Hence, the solution of the given quadratic equation are x = 0, -4 and -3.

Multiply. <br> 8 1/2 -2 2/3
MrRissso [65]

Answer: -\frac{68}{3} or -22\ 2/3

Step-by-step explanation:

To solve this problem you must:

- Convert the mixed numbers to fractions, as following:

8\ 1/2=\frac{((8*2)+1)}{2}=\frac{17}{2}

2\ 2/3=\frac{((3(2)+2)}{3}=\frac{8}{3}

- Multiply both fractions. Mutilply the numerators and the denominators:

(\frac{17}{2})(-\frac{8}{3})=-\frac{136}{6}

- Simplify. Therefore, you obtain that the answer is:

-\frac{68}{3} or -22\ 2/3
