A^5b -a
= a* (a^(5b-1) -1) (distributive property)
Now try backwards:
a* (a^(5b-1) -1)
= a* a^(5b-1) -a
= a^1* a^(5b-1) -a
= a^(5b-1+1) -a
= a^(5b) -a (correct).
The final answer is a* (a^(5b-1) -1)~
Answer:
Step-by-step explanation:
3x +4y= 8, where y =8x-20
3x + 4(8x - 20) =8
3x + 32x - 80 =8
3x +32x =8 +80
35x =88
x=88/35
x= 2.514
Answer: d. AB = CD and BC = AD
Step-by-step explanation:
We know that parallelogram is a quadrilateral with properties listed below:-
- The opposite sides are congruent ( AB = CD and BC = AD
).
- The opposite angels are congruent (∠A=∠C and ∠D=∠B).
- The consecutive angles are supplementary (∠A + ∠D = 180°).
- The diagonals of a parallelogram bisect each other.
- If one angle is right, then all angles are right.
It’s 0.6 because temper three can’t equally go into five.
