Answer:

x = 323 in

Step-by-step explanation:

Given triangles are similar, so their corresponding sides would be in proportion:

3ft = 3*12 = 36 in

5ft 8 in = 5*12 + 8 = 68 in

14 ft 3 in = 14*12 + 3 = 171 in

$\frac{3 \: ft}{14 \: ft \: 3 \: in} = \frac{5 \: ft \: 8 \: in}{x} \\ \\ \frac{36}{171} = \frac{68}{x} \\ \\ x = \frac{171 \times 68}{36} \\ \\ x = \frac{11628}{36} \\ \\ x = 323 \: in \: \\ \\ x = 26 ft \: 11 in$

Solve: 5 | x + 2 | + 2 > 7 The answer has the form: ( − ∞ , A ) ∪ ( B , ∞ ) ( A , B ) State your solution using interval nota

Given:

$5|x-3|+3>7$

Aim:

We need to find the value of x.

Explanation:

Subtract 3 from both sides of the equation.

$5|x-3|+3-3>7-3$

$5|x-3|>4$

Divide both sides of the equation by 5.

$\frac{5}{5}|x-3|>\frac{4}{5}$

$|x-3|>\frac{4}{5}$

Square both sides.

$(x-3)^2>(\frac{4}{5})^2$

$(x-3)^2>\frac{16}{25}$

$x^2-6x+9>\frac{16}{25}$

multiply

$x^2-6x+9>\frac{16}{25}$

Answer:

Step-by-step explanation:

$75^{30}\\\\75=3\cdot5\cdot5=3\cdot5^2\\\\75^{30}=(3\cdot5^2)^{30}=3^{30}\cdot(5^2)^{30}=3^{30}\cdot5^{60}$

$45^{45}\cdot15^{15}\\\\45=3\cdot3\cdot5=3^2\cdot5\\15=3\cdot5\\\\45^{45}=(3^2\cdot5)^{45}=(3^2)^{45}\cdot5^{45}=3^{90}\cdot5^{45}\\15^{15}=(3\cdot5)^{15}=3^{15}\cdot5^{15}\\\\45^{45}\cdot15^{15}=3^{90}\cdot5^{45}\cdot3^{15}\cdot5^{15}=3^{90+15}\cdot5^{45+15}=3^{105}\cdot5^{60}\\\\=3^{75+30}\cdot5^{60}=3^{75}\cdot\underbrace{3^{30}\cdot5^{60}}_{75^{30}}=3^{75}\cdot75^{30}$
