If h(x) = 2x^2 , then h(-2) + 5=_________
Vaselesa [24]

Answer:

13

Step-by-step explanation:

Given the equation h(x) = 2x²

To solve for h(-2) + 5 then, we need to break the problem into two parts

First, we will solve for the function h(x) at x = -2

h(x) = 2x² so

h(-2) = 2(-2)²

h(-2) = 8

Knowing this, we can plug 8 into our original expression for h(-2)

8 + 5

This gives us 13

How can you find the area of a two-dimensional composite figure, or the surface area of a three-dimensional composite figure?
goldenfox [79]

Step-by-step explanation:

<u>a. the area of a two-dimensional composite figure</u>

In this situation, we need to draw any necessary segments to view the figure as basic shapes, then:

  • Step 1: add basic shape areas belonging to the composite shape
  • Step 2: subtract basic shape areas NOT belonging to the composite shape

<u>b. the surface area of a three-dimensional composite figure</u>

As we know (3D) composite objects are made of two or more objects put together. To find the surface area of a 3D composite object, we need:

  • Step 1:  find the outside surface area of each object
  • Step 2: add the surface areas together

Hope it will find you well
