6 0

Simplifying 9e + -7 = 7e + -11
Reorder the terms: -7 + 9e = 7e + -11
Reorder the terms: -7 + 9e = -11 + 7e
Solving -7 + 9e = -11 + 7e
Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right.
Add '-7e' to each side of the equation. -7 + 9e + -7e = -11 + 7e + -7e Combine like terms: 9e + -7e = 2e -7 + 2e = -11 + 7e + -7e
Combine like terms: 7e + -7e = 0 -7 + 2e = -11 + 0 -7 + 2e = -11
Add '7' to each side of the equation.
Combine like terms: -7 + 7 = 0 0 + 2e = -11 + 7 2e = -11 + 7
Combine like terms: -11 + 7 = -4 2e = -4
Divide each side by '2'. e = -2
Simplifying e = -2

Square root of 648.7209 by division method

SpyIntel [72]

Answer:

$25.47$

Step-by-step explanation:

This root can be rewritten as:

$\sqrt{\frac{6487209}{10000} }$

$\sqrt{\frac{6487209}{100^{2}} }$

$\frac{1}{100}\cdot \sqrt{6487209}$

Since 6487209 is a multple of 3, the expression can be rearranged as follows:

$\frac{1}{100}\cdot \sqrt{3\times 2162403}$

2162403 is also a multiple of 3, then:

$\frac{1}{100}\cdot \sqrt{3^{2}\times 720801}$

$\frac{3}{100}\cdot \sqrt{720801}$

720801 is a multiple of 3, then:

$\frac{3}{100}\cdot \sqrt{3\times 240267}$

240267 is a multiple of 3, then:

$\frac{3}{100}\times \sqrt{3^{2}\times 80089}$

$\frac{9}{100}\cdot \sqrt{80089}$

80089 is a multiple of 283, then:

$\frac{9}{100}\cdot \sqrt{283^{2}}$

$\frac{9\times 283}{100}$

$\frac{2547}{100}$

$25.47$

How do I solve this

kap26 [50]

For 3 find the total area for the big semicircle, then find the area of the smaller one and subtract it. It would be the same for 4 but instead you find the total area of the square (24 x 24) and then subtract the semicircle are. (you were wrong on #4)
