B) If 3 + 5 = a, then a=3+5
C) 2 + b = b + 2
D) 3(2 + 5) = 6 + 15
Answer:
C)
Step-by-step explanation:
We are supposed to find which equations illustrates the commutative property.
Commutative property : The "Commutative Laws" say we can swap numbers over and still get the same answer i.e.
Substitute a =2
So,
So, Option C satisfies the law
Option A , B and D does not satisfies the law .
Only Option C is true .
Answer:
Step-by-step explanation:
We know that if two triangles are congruent , then the corresponding angles and sides are congruent by CPCTC.
Given:
Therefore , the corresponding angles and sides of are congruent.
∠F corresponds ∠H
∠M corresponds ∠Q
∠N corresponds ∠R
⇒ ∠F ≅ ∠H
∠M ≅ ∠Q
∠N ≅ ∠R
So , from the given options, the true congruency statements are :-
Answer:
the answer is b the solution is 6
Answer:
Speed = 55.56 m/s
Step-by-step explanation:
Given:
An airplane is travelling at the speed of 200 km/h.
We need to convert this in meter/second.
1 km = 1000 meters
1 hour = 3600 seconds
Speed = Distance/Time
Speed = (200*1000)/(1*3600)
= 200000/3600 meter/second
Speed = 55.56 m/s
Hope this will helpful.
Thank you.
Answer:
Step-by-step explanation:
g(x) = x^2 + 6
f(x^2 + 6) = 2(x^2 + 6) + 1 = 2x^2 + 12 + 1 = 2x^2 + 13
