Multiply both sides by c
X = d*c
52 ×.65= X
The answer would be $80. Hope i could be helpful :)
The answer to your question is C
B² = 8b + 84
b² - 8b - 84 = 0
b = <u>-(-8) +/- √((8)² - 4(1)(-84))</u>
2(1)<u>
</u>b = <u>8 +/- √(64 + 336)</u>
2
b = <u>8 +/- √(400)
</u> 2<u>
</u>b = <u>8 +/- 20
</u> 2
b = 4 <u>+</u> 10
b = 4 + 10 b = 4 - 10
b = 14 b = -6

1/49=x^2 where x is the side of the square
1/49=(1/7)^2, so the side length of the square is 1/7
