Subtract -5x^2 - 3 from -x - 5

Mathematics
1 answer:
Margarita [4]3 years ago
4 0
      -x-5
  -  -5x^2 - 3

or

(-x-5) - (-5x^2 - 3)

First, distribute the -. So then it becomes

-x - 5 + 5x^2 + 3

Since you can't add 5x^2 to -x. You can only combine -5 and 3.
Thus it becomes
 - x + 5x^2 -2

However, you order in exponents so

5x^2 - x - 2

would be the correct answer.

4= 6/a + 5 solve for x
Scorpion4ik [409]

Answer:

a=-6

Step-by-step explanation:

4= 6/a + 5

Subtract 5 from each side

4-5= 6/a + 5 -5

-1 = 6/a

Multiply by a on each side

-1*a = 6/a *a

-a =6

Multiply by -1

a= -6

What is the volume of a right trianular prism with the dimesions of 15 11 17
Harlamova29_29 [7]

Answer:

1402.5 Cubic Units

Step-by-step explanation:

Volume of a Triangular Prism: V = \frac{1}{2}bhl

b - base

h - height

l - length  

15 is the height, 17 is the length, and 11 is the width  (assuming which is the base).

V=0.5 * (11 * 15 * 17) \\V=0.5*2085\\V=1402.5

The volume of the prism should be 1402.5 cubic units.

A cube has how many vertices
Ulleksa [173]

Answer: 8 vertices

Step-by-step explanation: A cube has 6 square faces. Each segment formed by the intersection of 2 faces is called an edge so a cube has 12 edges. Each point formed by the intersection of 3 edges is called a vertex so a cube has 8 vertices.
