Answer:

$= 2x + (4 \times 36) - (4 \times x)$
$= 2x + 144 - 4x$
$= (2x - 4x) + 144$
$= - 2x + 144$
$= - 2( x - 72)$

Answer:

12 cm

Step-by-step explanation:

The Pythagorean Theorem is as follows:

$a^{2} +b^{2} =c^{2}$

A and B represent the side lengths (legs) and C represents the hypotenuse.

The length of one leg equals 5cm. (This can be represented by either a or b)

The hypotenuse equals 13 cm.

Plug these into the equation from above:

$a^{2} + (5^{2}) = (13^{2})$

Solve for the other leg:

$a^{2} + 25 = 169$ Square what's in the parentheses from above

$a^{2} = 144\\$ Subtract 25 from 169

$\sqrt{a^{2} } = \sqrt{144}$ Square root both sides

a = 12 cm

Thus, the length of the other leg is 12 cm.

Let's check our answer:

$12^{2} +5^{2} =13^{2}$ Square everything

144 + 25 = 169 Add

169 = 169

Because both sides are equal it means that 12 cm is the correct answer.

Hope this helps!!

Answer:

Step-by-step explanation:

$2x + 7 - 1 = 2x + 7$

$= > 2x - 1 = 2x + 7 - 7$

$= > 2x - 1 = 2x$

$= > - 1 = 2x - 2x$

$= > x = - 1$

Create a word problem that involves speed

lana66690 [7]

A hockey puck is sliding on frictionless ice on an infinite hockey rink.
Its speed is 36 km/hour. How far does the puck slide in 10 seconds ?

(36 km/hr) x (1,000 m/km) x (1 hr/3600 sec) x (10sec) =

(36 x 1,000 x 10 / 3,600) meters = <em>100 meters</em>

What is the puck's speed in miles per hour ?

(36 km/hr) x (0.6214 mi/km) = <em>22.37 mi/hr</em>
