Determine whether the sides given would form an acute, obtuse, or right triangle. 7, 7, 13

Brut [27]

Let a = 7 , b = 7, and c = 13. c is always the biggest number.

Acute Triangle is when $c^2 \ \textless \ a^2 + b^2$

Right Triangle is when $c^2 = a^2 + b^2$

Obtuse Triangle is when $c^2 \ \textgreater \ a^2 + b^2$

Jack has $6.00 less than twice the amount of money David has. Together they have $45.00. How much money does Jack have

Shalnov [3]

Answer:

Jack - $28

David - $17

Step-by-step explanation:

Jack has 2d-6 where d is David's money. David has d money. Together they have 45 and we add the two together.

2d-6+d=45

3d-6=45

3d=51

d=$17

We can then substitute back and find 2(17)-6=34-6=$28.
