3 0

4 is equal to 2*2 (double the 2 is 4)

We can get the value of 8*4 on two steps:
1- we multiply the 8 by 2
2- we add the result of the multiplication to itself

This is illustrated as follows:
8*2 = 16
16+16 = 32

im failing lol help The areas of the squares adjacent to two sides of a right triangle are 29.25 units^2 and 13 units ^2

Softa [21]

Answer and Step-by-step explanation:

To find the length of z, we need the lengths of the other 2 sides first. Simply take the square root of both areas and that will be your sides.

$\sqrt{13}$ and $\sqrt{29.25}$

Now find z, the hypotenuse.

$(\sqrt{13}) ^2 + (\sqrt{29.25} )^2 =z^2\\\\13 + 29.25 = z^2\\\\42.25 = z^2\\\\\sqrt{42.25} = z\\\\6.5 = z$

6.5 is the answer.

Solve for the variable Y: 3(y-6) less than or equal to 4(y+5)

enot [183]

I'll use the same notation as the other one:
3(y-6)<4(y+5)
I'm going to clean this up a bit by distributing:
3y-18<4y+20
Now, subtract 3y from both sides:
-18And now, subtract 20:
-38So y is greater than or equal to -38
Hope this helps!
