Answer:

x = √72 and yes, it forms a Pythagorean triple

Step-by-step explanation:

a^2 + b^2 = c^2,

3 is a, x is b, anf 9 is c

3^2 + x^2 = 9^2

9 + x^2 = 81

Subtract 9 from both sides

x^2 = 72

x = √72

a Pythagorean triple is a^2 + b^2 = c^2, and this has it

Answer:

X = 9.4

Step-by-step explanation:

Pythagorean Theorem:

<u>Formula: a² + b² = c²</u>

  • 9 x 9 = 81

Please helppp<br><br> (750/512)^1/3 <br> what is equivilant to this??
Misha Larkins [42]
\bf a^{\frac{{ n}}{{ m}}} \implies  \sqrt[{ m}]{a^{ n}} \qquad \qquad&#10;\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\&#10;-------------------------------

\bf \left( \cfrac{750}{512} \right)^{\frac{1}{3}}\implies \cfrac{750^{\frac{1}{3}}}{512^{\frac{1}{3}}}\implies \cfrac{\sqrt[3]{750^1}}{\sqrt[3]{512^1}}\quad &#10;\begin{cases}&#10;750=2\cdot 3\cdot 5\cdot 5\cdot 5\\&#10;\qquad 2\cdot 3\cdot 5^3\\&#10;\qquad 6\cdot 5^3\\&#10;512=8\cdot 8\cdot 8\\&#10;\qquad 8^3&#10;\end{cases}&#10;\\\\\\&#10;\cfrac{\sqrt[3]{750}}{\sqrt[3]{512}}\implies \cfrac{\sqrt[3]{6\cdot 5^3}}{\sqrt[3]{8^3}}\implies \cfrac{5\sqrt[3]{6}}{8}

Simplify the following expression, 4.2x+4.7=18.6
zhannawk [14.2K]

Answer:

Step-by-step explanation:

4.2x+4.7=18.6

Multiple each term by 10

42x + 47 = 186

Collecting like terms

42x = 186 - 47

42x = 139

x = 139/42

x = 3 13/42 or 3.3
