Find the surface area of this net.
Elden [556K]

Answer:

<h2>231cm²</h2>

Step-by-step explanation:

First, let's find the surface area of both the triangles

5x3=15

So, the surface area of the triangles is 15 sq.cm

Now, let's find the surface area of the base (large rectangle in the middle)

12x8=?

10x8=80

2x8=16

80+16=96

12x8=96

So, the surface area of the base, is 96sq.cm

Now, let's find the surface area of both of the side rectangles

12x5=60

60x2=120

So, the surface area of the two side rectangles is 120sq.cm

Now, let's find the total surface area by adding all of our answers.

120+96=216

216+15=231

<h2>So hence, the surface area of this net is 231cm²</h2>

What is the slope-intercept form of the function described by this table
-BARSIC- [3]

Answer:

y = - 3x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (3, - 5) ← 2 ordered pairs from table

m = \frac{-5-1}{3-1} = \frac{-6}{2} = - 3, thus

y = - 3x + c ← is the partial equation

To find c use any ordered pair from the table

Using (3, - 5 ), then

- 5 = - 9 + c ⇒ c = - 5 + 9 = 4

y = - 3x + 4 ← equation of line
