A slope is rise over run.

From the triangle ABC, slope = AB/BC,

and from the triangle CDE, slope=CD/DE.

And the slope is the same, AB/BC = CD/DE.

Answer : AB to BC is equal to the ratio CD to DE.

I need help ASAP! Plz ( Thank You )

Answer:

6a) x = -6

Let's solve your equation step-by-step.


14= 2x + 26


Step 1: Flip the equation.


2x + 26 = 14


Step 2: Subtract 26 from both sides.


2x + 26 − 26 = 14 − 26


2x = −12


Step 3: Divide both sides by 2.


2x/2 = −12/2


x=−6

--------------------

7a) x = 4.25

Let's solve your equation step-by-step.


−30 =4 − 8x


Step 1: Simplify both sides of the equation.


−30 = 4 − 8x


−30 = 4 + −8x


−30 = −8x + 4


Step 2: Flip the equation.


−8x + 4 = −30


Step 3: Subtract 4 from both sides.


−8x + 4 − 4 = −30 − 4


−8x = −34

x=17/4 (Decimal: 4.25)

---------------------------------

8a) x = 8

Let's solve your equation step-by-step.


3(x − 4) = 12


Step 1: Simplify both sides of the equation.


3(x − 4) = 12


(3)(x) + (3)(−4)= 12(Distribute)


3x + −12 = 12


3x − 12= 12


Step 2: Add 12 to both sides.


3x − 12 +1 2 = 12 + 12


3x = 24


Step 3: Divide both sides by 3.

3x/3=24/3

x=8

A triangular prism has a base of 9 and height of 7. The length of each side of the triangular prism is 9 and the width of the en
Sergio [31]

Answer:

Therefore,

The surface area is

\textrm{Total Surface Area of Prism}=252\ units^{2}

Step-by-step explanation:

Shape is triangular prism,

Base = b = 9

Height = h = 7

The length of each side of the triangular prism ,

s₁ = s₂ = s₃ = 9

Width of the entire prism

Width = W = 7

To Find:

The surface area = ?

Solution:

Total Surface Area of Prism is given by,

\textrm{Total Surface Area of Prism}=bh + (s_{1}+s_{2}+s_{3})W

Where,

b = Base

h = Height

s₁ , s₂ , and s₃ = length of each side of the triangular prism

W = width of the prism

Substituting the values we get

\textrm{Total Surface Area of Prism}=9\times 7 + (9 + 9 + 9)\times 7=252\ units^{2}

Therefore,

The surface area is

\textrm{Total Surface Area of Prism}=252\ units^{2}
