Answer:
185
Step-by-step explanation:
60(1 hour)+90(45x2hours)+35(1 hour)= 185
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.

Answer:
D from A = 34 miles
Step-by-step explanation:
We know the total distance is 200 miles (this would be when they meet)
The rate for cyclist A is 17
The rate for cyclist B is 83
We know the time is equal
Distance = rate * time
Distance for A = 17t
Distance for B = 83 t
The total distance = distance for A + distance for B
200 = 17t + 83t
Combine like terms
200 = 100t
Divide each side by t
200/100 = 100t/100
They will meet at t =2 hours
I know you say we need the distance
Distance for A
D = 17*t
We now know t
D = 17*2
D = 34 miles
Answer:
r = p(-b/a)
Step-by-step explanation:
Let p(x) = q(x)(ax + b) + r(x) where q(x) is the quotient when p(x) is divided by ax + b and r(x) is the remainder.
Since ax + b is a first degree polynomial, r(x) is one power less than ax + b is is just a constant, r.
So, p(x) = q(x)(ax + b) + r
Now, p(x) = r when q(x)(ax + b) = 0
since q(x) ≠ 0, ax + b = 0 ⇒ ax = -b ⇒ x = -b/a
⇒ p(x) = r when x = -b/a
So, r = p(-b/a)
So, the remainder when a polynomial function p(x) is divided by a first degree polynomial ax + b is p(-b/a)
