I think it's -35. The steps to get that number is subtracting the 3 to the right side. Then you have -2 - 3 which equals to -5. Then you still have x/7= -5. Get rid of 7 from the x and do the same thing to the other side but you multiply 7 and -5. Last you your would be x= -35.
Answer:
See below.
Step-by-step explanation:
From the given info the 2 triangles are isosceles with AE = FR and ET = RP because the 2 sets of base angles are equal.
As the base angles are congruent m < E = m < R.
So the are 2 triangles are congruent by SAS, ASA and AAS.
Answer:
(x - 5) (x + 1)
Step-by-step explanation:
x² - 4x - 5
= x² + x - 5x - 5
= x(x + 1) - 5(x + 1)
= (x - 5) (x + 1)
It is a polynomial, and the degree is quartic
hope this helps
Answer:
Speed of car B is 33 km/h and speed of car A is 
Step-by-step explanation:
Let speed of car B be 
km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A = 
km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours = 
km = 
km
Distance travelled by car B in 4 hours = 
km
Also, cars A and B are 312km apart after 4 hours.
Speed of car B is 33 km/h and speed of car A is
