Answer:
(a^8)/(b^9)
Step-by-step explanation:
Two rules of exponents come into play.
(a^b)/(a^c) = a^(b-c)
a^-b = 1/a^b
__
Applying the first rule, we have ...
(a^3)/(a^-5) × (b^-2)/(b^7) = a^(3 -(-5)) × b^(-2 -7) = a^8 × b^-9
Applying the second rule gives the simplified form ...
= (a^8)/(b^9)
The answer is irregular because speak is the base word and spoke is its past word
Answer:
a) 7x^2 + 5x
Step-by-step explanation:
(9x^2 + 8x) – (2x^2 + 3x)
Distribute the minus sign
(9x^2 + 8x) – 2x^2 - 3x
Line them up vertically
(9x^2 + 8x)
– 2x^2 - 3x
-------------------
7x^2 +5x
Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
Answer:
none
Step-by-step explanation:
No choice is correct.
The original expression has 560 x 70, the product of 560 and 70 inside the parentheses.
(560 x 70) ÷ 10 is 10 times smaller than 560 x 70
None of the choices show 560 x 70. They show 560 + 70 and 560 - 70.
Answer: none
