Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}

Step-by-step explanation:

Let the number be 'x'

Create an equation

\sf{ {x}^{2}  = 49}

Squaring on both sides

\dashrightarrow{ \sf{ \sqrt{ {x}^{2} }  =  \sqrt{49} }}

\dashrightarrow {\sf{ \: x = 7}}

Hope I helped!

Best regards!

Kamila [148]

Answer:

Shaquille O'Neal's height= 2,160,000,000 nm

= 2.16 × 10^9 nm

Completed question;

The basketball player Shaquille O'Neal is 7 feet 1 inch tall, which is equivalent to 216 centimeters a nanometer (nm) is a unit of measurement that is one-billionth of a meter, convert his height to nanometers.

Step-by-step explanation:

Given;

Shaquille O'Neal's height= 216cm = 216 × 1/100 m = 2.16m

Since, a nanometer (nm) is a unit of measurement that is one-billionth of a meter.

1 m = 1 billion nanometers

So,

2.16m = 2.16 billion nm = 2160000000 nm

Shaquille O'Neal's height= 2160000000 nm

= 2.16 × 10^9 nm

1 matrix question help (with picture)
Dominik [7]

Answer:

  a = 9/2

Step-by-step explanation:

In order for the equation to be true, the value of the scalar multiplier must be ...

  15/3 = -10/-2 = 35/7 = 5

So, you're solving ...

  (2/3)a + 2 = 5

  (2/3)a = 3 . . . . . . subtract 2

  a = 9/2 . . . . . . . . multiply by 3/2
