Could some please help me with these two

Mathematics
1 answer:
damaskus [11]3 years ago
4 0

Answer:

+3

Step-by-step explanation:

(-m)^(-3) = -m^3, since (-1)^-3 = 1 / (-1).

If m = 2 then we have -2^(-3), or  -1 / [2^3]), or -1/8.

Finally, if n = -24, the original expression becomes

(-1/8)(-24) = +3

Second problem:  Only the first expression simplifies to a negative result.

Work out the value of x.<br>Need answer soon :) ​

Answer:

x+20

Step-by-step explanation:

As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.

So we plug everything in and we have  4x+5x=180 degrees

4x+5x=9x, so 9x=180

We divide by 9 on both sides to get the value of x, which is 20

Hope it helps!

Which is a true statement about an isosceles right triangle?
AnnyKZ [126]

Let l be the length of a leg. Using the pythagorean theorem, the hypotenuse is

h = \sqrt{l^2+l^2}=\sqrt{2l^2}=l\sqrt{2}

So, the hypotenuse is \sqrt{2} times as long as either leg.
