The sum of 8n^2-3n+10 and -3n^2 -6n-7 is

Mathematics

8n^2-3n+10 + -3n^2-6n-7

8n^2 + -3n^2 = 5n^2

-3n + -6n = -9n

10 + -7 = 3

Put them all together and you get 5n^2-9n+3

I tried to space them out so that it makes more sense.

2 (x – 4) = -5<br> How do I do this
DanielleElmas [232]

Step-by-step explanation:

your going to distribute the 2 to the x and the four your equation will then become (2x-8)=-5 you would then do the opposite of subtraction which is add so add +8 to the -8 and that cancels it out then you would +8 to the -5 and get 2x=3 then I'm confused from there hope that helps kinda

In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?
lana [24]

Answer:

= 15.556 in

Step-by-step explanation:

Since this is a 45-45-90 triangle, we can tell that;

  • This is a right triangle  
  • This is an isosceles triangle

One of the theorems of geometry, the Isosceles Right Triangle Theorem, says that the hypotenuse is √2 times the length of a leg.

Therefore;

hypotenuse = leg × √2

If we take hypotenuse as x

Since the leg is 11;

Then; x = 11√2

x = 11/√2

x = 15.556 in
