Anyone have a answer for this?
LiRa [457]

Answer:

36.1 meters

Step-by-step explanation:

Since this is a rectangle, the parallel sides are equal to each other, meaning we technically already know all the side lengths.

I'll choose to look at the bottom triangle in this case

30 is already there, and the other leg should be 20. Knowing this, we can plug these into the pythagorean theorem.

20 is A, 30 is B, and the missing side is C

a^{2} + b^{2} = c^{2}\\20^{2}  + 30^{2} = c^{2} \\400 + 900 = 1300 \\\sqrt{1300} = 36.06\\

C, the missing side to the nearest tenth is 36.1 meters

20 points<br> What is the value of p in the linear equation ?<br><br> −4<br> −2<br> 2<br> 4
Nikolay [14]

Answer:

p=-2

Step-by-step explanation:

24p+12-18p=10+2p-6  

Subtract what is to the right of the equal sign from both sides of the equation.

24p+12-18p-(10+2p-6)=0

Then pull out the like terms(factors)

Which is: 4p+8

=4(p+2)

Put that to 0 and 4=0 which is not a solution because it's a non-zero constant.

So now put  p+2=0, subtract by 2 on both sides and the 2 cancels out and on the right side you have -2

p=-2
