Root of 2i also means there is a root of -2i
Root of 3i also means there is a root of -3i

Factors will be (x^2 + 4)(x^2 + 9).
Multiply this out to get the polynomial:
x^4 + 13x^2 + 36

Kamilah’s weight has tripled since her first birthday. If w represents the amount Kamilah weighed on her first birthday, write a
S_A_V [24]

Answer:

3*w

Step-by-step explanation:

Kamilah now weighs the triple of what she weighed on her first birthday. That means we need to multiply the first weight by 3. As the first weight is w, she now weighs 3*w.

Another possible expression is to sum 3 times w, that is w + w + w (it's equal to 3*w).

A slice of cheese is shaped like a right triangle, with a hypotenuse of 25 mm and a height of 24 mm. How wide is the cheese?
Firlakuza [10]
7 mm wide

To solve this, you can use the Pythagorean theorem.

A triangle's sides is length squared + length squared = hypotenuse squared. We know the hypotenuse and one side of the triangle. So, we can follow the equation 24 squared + x squared = 25 squared

To solve this, find the value of 24 squared and 25 squared. 24 squared = 576, and 25 squared = 625, so your equation becomes 576 + x squared = 625

Next, you subtract your known values. 576 + x squared – 576 = 625 – 576 = 49, so x squared = 49

For the last step, find the square root (√) of 49, which is 7. So x = 7 mm

And you can check: 24 squared + 7 squared = 25 squared
