1. Can cross multiplication be used to solve this problem? Why or why not?<br><br><br> HELP
garri49 [273]

Answer:

Step-by-step explanation:

Cross multiplication can be used but not in the beginning. First x should be isolated.

3 +\frac{5}{x}=\frac{7}{x}\\\\

Now subtract \frac{5}{x} from both sides

3 = \frac{7}{x}-\frac{5}{x}\\\\3=\frac{7-5}{x}\\\\3=\frac{2}{x}

In this stage, cross multiplication can be used.

\frac{3}{1}=\frac{2}{x}\\\\3*x=2*1\\\\x = \frac{2}{3}

BartSMP [9]
<h3>Answer:</h3>

\large\boxed{\sqrt{120x^{15}}=2x^7\sqrt{30x}}

<h3>Step-by-step explanation:</h3>

Domain:\ x\geq0\\\\\sqrt{120x^{15}}=\sqrt{4\cdot30\cdot x^{14+1}}\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=\sqrt{4\cdot30\cdot x^{14}\cdot x^1}\\\\\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\\\=\sqrt4\cdot\sqrt{30}\cdot\sqrt{x^{14}}\cdot\sqrt{x}=2\cdot\sqrt{30}\cdot\sqrt{x^{7\cdot2}}\cdot\sqrt{x}\\\\\text{use}\ (a^n)^m=a^{nm}\\\\=2\cdot\sqrt{30}\cdot\sqrt{(x^7)^2}\cdot\sqrt{x}\\\\\text{use}\ \sqrt{a^2}=a\ \text{for}\ a\geq0\\\\=2\cdot\sqrt{30}\cdot x^7\cdot\sqrt{x}=2x^7\sqrt{30x}

The equation a2 + b2 = ca represents the relationship between the three sides of a right triangle.
choli [55]

Answer:

Step-by-step explanation:

I think you mean a² + b² = c², not ca.

a = 10, c = 26

b² = c²  - a² = 26² - 10² = 576

b = √576 = 24 ft
