Answer:
Step-by-step explanation:
to find increased percent
increase amount = $70 - $40
=$30
increase percent = increase amount /original amount *100%
=30/40 *100%
=3000/40
=75%
to find decrease percent
decrease amount = $70 - $40
=$30
decrease percent = decrease amount /original amount *100%
=30/70 *100%
=3000/70
=42.85 %
1. x^2-16x+c
2. p^2-14p+c
3. b^2+18b+c
4. n^2-n+c
Answer: 3²
Step-by-step explanation: In this problem, notice that our 3's are bases. So as we apply the quotient rule to divide these two powers, we subtract the exponents but leave the base alone.
So 3⁴ / 3² = 3².
25x2 − 16
25x2 + 16
25x2 − 40x + 16
Answer:
25x^2 + 40x + 16
Step-by-step explanation:
(5x + 4)^2
= (5x + 4)*(5x + 4)
= 25x^2 + 20x + 20x + 16
= 25x^2 + 40x + 16
