Perimeter is the length of the whole outside of the shape, in this case the perimeter is 38. 7+7= 14 and 12+12= 24, 14+24= 38
Answer:
Tthe distance between the police station and the fire station is 4 miles
Step-by-step explanation:
Let's call x the distance between the library and the police station
Let's call z the distance between the police station and the fire station
We know that:
miles
The distance (x) between the library and the police station is 3 miles less than twice the distance (z) between the police station and the fire station
This is:
We wish to find the distance z.
Then we equate both equations and solve for the variable z
Answer: Let c represents the time spends in producing a cockpit and p represents the time spends in producing a propulsion system. Thus, According to the question, Machine A ran for 26 hours and produced 4 cockpits and 6 propulsion systems.⇒ 4 c + 6 p = 26And, Machine B ran for 56 hours and produced 8 cockpits and 12 propulsion systems,⇒ 8 c + 12 p = 56Hence, the system of equations that will be used to find a unique amount of time that it takes each machine to produce a cockpit and to produce a propulsion system is,4 c + 6 p = 26, 8 c + 12 p = 56But both lines are parallel,Hence there is no solution of this system,Therefore, we can not solve for a unique amount of time that it takes each machine to produce a cockpit and to produce a propulsion system.

Step-by-step explanation:
Let be the measure of one angle in our triangle; since we have two equal angles in our triangle, their measure will be .
We know from our problem that at least one angle of our triangle measure 52°; since the sum o the interior angles of a triangle is 180°, we can use an equation to relate the quantities and solve for to find the measure of the tow equal angles:
Now how know that the measure of the angles of our triangle are 52°, 64°, and 64°. Since we have tow equal angles in our triangle, we can conclude that our triangle is isosceles. Notice that we don't have any given side, so the sides of our isosceles triangle can vary in length.
We can conclude that the correct answer is: C. Exactly one triangle exists with the given conditions, and all instances must be isosceles triangles.
