How many triangles can you make from straws with the lengths 2,1,2 inches?

Mathematics

marysya [2.9K]3 years ago
6 0

Answer:

You can make one triangle with these lengths

Step-by-step explanation:

we know that

The <u>Triangle Inequality Theorem</u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Verify if the lengths satisfy the triangle inequality theorem

1) 2+1 > 2

3 > 2 ------> is true

2)2+2 > 1

4 > 1 -----> is true

so

The lengths  satisfy the triangle inequality theorem

therefore

You can make one triangle with these lengths

What is the solution of the system? Use the elimination method. 2x+y=206x−5y=12 Enter your answer in the boxes.
astraxan [27]

Answer:

The answer to your question is:   x = 7; y = 6

Step-by-step explanation:

                                             2x+y=20             ( 1 )  Multiply by 5

                                             6x−5y=12            ( 2 )

                               5 (2x+y=20)    = 10x + 5y = 100

                                          10x + 5y = 100

                                            6x − 5y =   12             Eliminate y

                                          16 x        = 112

                                           x = 112 / 16

                                           x = 7

                                 2(7) + y = 20                 Substitution

                                 14 + y = 20

                                 y = 20 - 14

                                 y = 6

The sign of the<br> product of -21 and 451 is
Alexxx [7]

The sign of the product of -21 and 451 is going to be negative. That is because of the rule when you are multiplying a positive number times a negative number. A positive number times a negative number will always be negative. Here are some helpful rules to know:

positive * positive = positive

negative * positive = negative

negative * negative = positive (the negatives cancel each other out)

Since this question has numbers that fit the second case, the answer will be negative.
