Btw sry I know my handwriting sucks
so I'm guessing they want us to assume that OKM is splitting the right angle perfectly in half otherwise they would label it and so therefore that is why I'm splitting them in half (half of ninety is forty five) also just thought I'd add a pic showing the angles. I hope this helps

Can somebody help me find the zeroes for this, algebraically?

Natalija [7]

To solve this algebraically, you can first factor out a 3:
$3(x^2-2x-8)$

Then, you can factor (I'm using guess and check) and my answer is -4 and 2: $3(x-4)(x+2)$

From here on, finding 0s is very easy. You just solve for x in the parentheses. So, the 0s are when x = 4, and x = -2. Remember, (4-4) = 0, and (-2+2) = 0, that's what you want.

What is the volume of a cube that has a side length of 5 centimeters? A cube with side lengths of 5 centimeters. Recall the form

Mashutka [201]

Answer:

125 cm^3

Step-by-step explanation:

To calculate this volume, we make use of the formula for calculating the volume of a cube.

Mathematically, this is equal to L^3 where L is the length of a side of the cube.

plugging the value of 5 into the equation, the volume will be 5 * 5 * 5 = 125 cm^3
