$\bf \stackrel{eg}{5x+8}-\stackrel{fg}{3x}=\stackrel{ef}{6x-4}\implies2x+8=6x-4\implies 12=4x
\\\\\\
\cfrac{12}{4}=x\implies 3=x\qquad \qquad \stackrel{ef}{6(3)-4}$

and surely you know how much that is.

What is the longest line segment that can be drawn in a right rectangular prism that is 14cm long, 13cm wide, and 11cm tall?

vlabodo [156]

The longest line segment that can be drawn in a right rectangular prism that is 14cm long, 13cm wide and 11cm tall is 19.1cm.

<h3>What is a right rectangular prism?</h3>

A right rectangular prism is a three dimensional solid shape formed by 6 rectangles.

it is also called the cuboid.

Analysis:

The diagonal of the face of the prism with dimensions 14cm long and 13cm wide is the longest line segment that can be drawn.

Since rectangles have 90° on each vertex, we can use Pythagoras theorem to calculate for the length of the diagonal.

$(diagonal)^{2}$ = $(length)^{2}$ + $(width)^{2}$

$(diagonal)^{2}$ = $(14)^{2}$ + $(13)^{2}$

= 196 + 169 = 365

$(diagonal)^{2}$ = 365

diagonal = $\sqrt{365}$ = 19.1cm

In conclusion, the length of the longest diameter is 19.1cm

The limit as x-approaches 3 of f(x) is x-3 over x squared -9

Luden [163]

notice that the denominator can be factored into (x-3)(x+3).

Now you can cross out (x - 3) from the numerator and denomiantor resulting in a simplified fraction of $\frac{1}{x+3}$

Plug the limit value (which is 3) into the simplified fraction.

Answer: $\frac{1}{6}$

The sum of three consecutive odd integers is 17 less than four times the smallest integer

Lilit [14]

$x = smallest \: int \\ x + (x + 2) + (x + 4) = 4x - 17 \\ 3x + 6 = 4x - 17 \\ 23 = x \\ numbers = 23 \: 25 \: 27$

You move down 6 units. You end at (-5, -5). Where did you start?

torisob [31]

Answer:

(-5, 1)

Step-by-step explanation:

(x, y)

x moves left/right

y moves up/down

x = -5

y = -5 + 6 = 1

(-5, 1)

. How are the formulas for the circumference of a circle and area of a circle derived?

kakasveta [241]

They can be derived by using calculus(integration to be precise)

$\pi$ $= \frac{circumference }{diameter}$ (its how pi is defined)
so that gives circumference

to get area , you use integration $of an elemental ring of radius r and thickness dr and integrate it$ $A= \int\limits^0_r {2 \pi r} \, dr$

that gives the area.

if you don't know calculus yet ,dont worry, just remember the formulae.
