Sorry I'm dum,b and don't know scientific notation very well please explain for brainly =D
yuradex [85]
The simplest I can put it

10^1 = 10
10^2 = 100
10^3 = 1000
(essentially the number of zeroes)

5*10^2 = 5*100 = 500 (adding 2 zeroes, or moving the decimal over 2 places

Same works for numbers smaller than zero

5*10^-2 = 5*.01 = .05 (moving the decimal to the right 2 places

What is the value of x?
sladkih [1.3K]
If the angles are 90,45,45 so the sides except hypotenuse are congruent
and the hypotenuse is equal to :
{6 \sqrt{2} }^{2}  +  {6 \sqrt{2} }^{2}  =  {x}^{2}  \\  {8.5}^{2}   +  {8.5}^{2}  =  {x}^{2}  \\ 72.25 + 72.25 =  {x}^{2}  \\
{x}^{2}  = 144.5 \\ x = 12

I need the help alot​
GuDViN [60]

Answer:

{-5/4, 8}

Step-by-step explanation:

We are given (4u + 5)(8 - u) = 0.  Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:

4u + 5 = 0 leads to u = -5/4, and

8 - u = 0 leads to u = 8.

The solutions are {-5/4, 8}
