Answer:BRAINLIEST PLS

x2=64

Step-by-step explanation:

x2=64

Step 1: Take square root.

x=±√64

x=8 or x=−8

Answer:

x=8 or x=−8

factoring

x2=64

Step 1: Subtract 64 from both sides.

x2−64=64−64

x2−64=0

Step 2: Factor left side of equation.

(x+8)(x−8)=0

Step 3: Set factors equal to 0.

x+8=0 or x−8=0

x=−8 or x=8

A suspension bridge has two main towers of equal height. A visitor on a tour ship

Scilla [17]

Answer:

The Height of the tower is 188.67 ft

Step-by-step explanation:

Given as :

The angle of elevation to tower = 15°

The distance travel closer to tower the elevation changes to 42° = 497 ft

Now, Let the of height of tower = h ft

The distance between 42° and foot of tower = x ft

So, The distance between 15° and foot of tower = ( x + 497 ) ft

So, From figure :

In Δ ABC

Tan 42° = $\frac{perpendicular}{base}$

Or , Tan 42° = $\frac{AB}{BC}$

Or, 0.900 = $\frac{h}{x}$

∴ h = 0.900 x

Again :

In Δ ABD

Tan 15° = $\frac{perpendicular}{base}$

Or , Tan 15° = $\frac{AB}{BD}$

Or, 0.267 = $\frac{h}{( x + 497 )}$

Or, h = ( x + 497 ) × 0.267

So, from above two eq :

0.900 x = ( x + 497 ) × 0.267

Or, 0.900 x - 0.267 x = 497 × 0.267

So, 0.633 x = 132.699

∴ x = $\frac{132.699}{0.633}$

Or, x = 209.63 ft

So, The height of tower = h = 0.900 × 209.63

Or, h = 188.67 ft

Hence The Height of the tower is 188.67 ft Answer

Which of these is a correct expansion of (4x - 2)(2x + 3)?

RideAnS [48]

Answer:

It's 8x²+8x-6

Step-by-step explanation:

If you multiply each component you get:

4x * 2x = 8x²

4x * 3 = 12x

-2 * 2x = -4x

-2 * 3 = -6

Adding everything you have the result.
