Answer:
Step-by-step explanation:
Use proportions to solve.
Corresponding sides have same ratio.
<u>Question 1</u>
- (6x + 3)/17 = (8x - 1)/21
- 21(6x + 3) = 17(8x - 1)
- 126x + 63 = 136x - 17
- 10x = 80
- x = 8
<u>Question 2</u>
- (x + 8)/21 = 32/28
- x + 8 = 21*8/7
- x + 8 = 24
- x = 24 - 8
- x = 16
Percent of Change:
Difference/Original
(20-16)/16 = 4/16 = 1/4 = 25% increase
<span>x2 − 8x + 16
= (x - 4)(x - 4)
= (x - 4)^2</span>

got it right :) hope this helped
Answer:
The ones that can be used are (B and A)
The ones that cannot be used are (C and D)
Step-by-step explanation:
Because the panthers got 6 less and the tigers got 22…
b+6 would make 22 (panthers plus 6 makes tigers)
22-b would also be 6 because 6+b makes 22, so subtracting b from 22 makes 6
