Anthony Drew plans for a triangle porch determine if the triangle can be made justify your response​
garik1379 [7]

The triangle cannot be made.

Solution:

Given sides of a triangle are 8 ft, 20 ft and 8 ft.

<u>To determine if the triangle can be made:</u>

Let us first define the triangle inequality theorem.

Triangle inequality theorem:

The sum of the lengths of the any two sides of a triangle is greater than the length of the third side.

Using this theorem, we can determine if the triangle can be made or not.

8 ft + 20 ft = 28 ft > 8 ft

20 ft + 8 ft = 28 ft > 8 ft

8 ft + 8 ft = 16 ft < 20 ft  

Here the sum of the two sides is less than 20 ft.

This is not satisfy the triangle inequality theorem.

Therefore, the triangle cannot be made.

What are the solutions to the equation -5x2 + 3x = -9
Aleks04 [339]

Answer: Move terms to the left side−52+3=−9−5x2+3x=−9−52+3−(−9)=0−


Common factor−52+3+9=0−5x2+3x+9=0−(52−3−9)=0


Divide both sides by the same factor−(52−3−9)=0−(5x2−3x−9)=052−3−9=0


Solution=3±321 over 10

Create a matrix that is equal to F+G. The first matrix below is named F and the second matrix below is named G. Name the new mat
likoan [24]

F+G:

F+G=\begin{bmatrix}{-1.8} & {-8.6} & {} \\ {2.85} & {-1.4} & {} \\ {-1.8} & {5.1} & {}\end{bmatrix}+\begin{bmatrix}{1.32} & {-1.9} & {} \\ {2.25} & {0.0} & {} \\ {-6.2} & {1.4} & {}\end{bmatrix}

Then, add the elements that occupy the same position:

H=\begin{bmatrix}{-1.8+1.32} & {-8.6+(-1.9)} & {} \\ {2.85+2.25} & {-1.4+0.0} & {} \\ {-1.8+(-6.2)} & {5.1+1.4} & {}\end{bmatrix}

Solve

H=\begin{bmatrix}{-0.48} & {-10.5} & {} \\ {5.1} & {-1.4} & {} \\ {-8} & {6.5} & {}\end{bmatrix}

So, we find the element at address h31:

H=\begin{bmatrix}{h11} & {h12} & {} \\ {h21} & {h22} & {} \\ {h31} & {h32} & {}\end{bmatrix}

In this case, position h31 is - 8.0
