Answer/Step-by-step explanation:

Volume = l*w*h

or in this case a*b*c

A*B = 5*2 = 10

Ab = 10

10* C = 10*7 = 70

ABC = 70^3 or 70 cubic units

<h2>Answer : C. 70 cubic units</h2>

What is the answer I really need help

attashe74 [19]

Answer: 27

Step-by-step explanation:

The perimeter is the lengths of all sides of the figure added together. Since all sides are equal in this triangle, we know all sides have a length of 9. We know this because all sides have 2 little lines on them, symbolizing that they are equal.

P=9+9+9=27

What are the zeros of the function f(x) = x2 + 5x + 5 written in simplest radical form?

Pavel [41]

$\boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

<h2>Explanation:</h2>

Using the quadratic formula:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ \\ Here: \\ \\ f(x) = x^2 + 5x + 5 \\ \\ \\ So: \\ \\ a=1 \\ \\ b=5 \\ \\ c=5 \\ \\ \\ x=\frac{-5 \pm \sqrt{5^2-4(1)(5)}}{2(1)} \\ \\ x=\frac{-5 \pm \sqrt{25-20}}{2} \\ \\ x=\frac{-5 \pm \sqrt{5}}{2} \\ \\ \\ Two \ solutions: \\ \\ \boxed{x_{1}=\frac{-5 + \sqrt{5}}{2}} \\ \\ \\ \boxed{x_{2}=\frac{-5 - \sqrt{5}}{2}}$

The simple interest is $300.

Step-by-step explanation:

<em>Find the Interest amount.</em>

I: Interest ?

P: Principle Amount $2500

R: Rate 6% = .06

T: Time Period (in years) 2 Years

<em>Convert into equation to find Simple Interest</em>

I = Prt

I = (2500)(.06)(2)

<em>Calculate</em>

I = 300
