irakobra [83]

Answer:

10, 5, 19

Step-by-step explanation:

Recall that

${a}^{2} - {b}^{2} = (a + b)(a - b)$

So we can multiply the fraction by

$\frac{2 \sqrt{5} + 1 }{2 \sqrt{5} + 1 }$

And get

$\frac{ \sqrt{5} }{2 \sqrt{5} - 1} \times \frac{2 \sqrt{5} + 1 }{2 \sqrt{5} + 1 } = \frac{10 + \sqrt{5} }{20 - 1} = \frac{10 + \sqrt{5} }{19}$

Walt and Hank collect quarters from different states. Walt collected q quarters. Hank collected four fewer quarters than Walt. T

SpyIntel [72]

Answer:

Walt has 37 quarters. Hank has 33.

Step-by-step explanation:

Solve the given equation for q:

0.25q + 0.25q - 1.00 = 17.50

Simplify this, obtaining:

0.50q = 18.50

Simplifying this by multiplying both terms of this result by 100:

50 q = 1850

Thus, q = 1850/50 = 37

Walt has 37 quarters. Hank has 33.

Note that 37 + 33 = 70, and that 70($0.25) = $17.50. So our results are correct.

ahrayia [7]

Answer:

Step-by-step explanation:

X = 26 ; y = 27

(x − y)2 = x² − 2xy + y²

(26 - 27)² = 26² - 2(26)(27) + 27²

(-1)² = 676 - 1404 + 729

1 = 1405 - 1404

1 = 1
