A rectangle has a perimeter of 44 inches and it is 4 inches longer than it is wide what is the area of the rectangle

morpeh [17]

Answer:

117 inches squared

Step-by-step explanation:

perimeter= 44 inches

L=W+4

44=w+w+(w+4)+(w+4)

44=4w+8

36=4w

9=width

9+4=13

width=9

Length=13

area=L*W

13*9=117

Find all the values of x in the set of complex numbers that satisfy the following equation:

Fynjy0 [20]

Compute all the component integrals first:

$I_1=\displaystyle\int_0^{\pi/4}2\sec x\,\mathrm dx=2\ln(\sqrt2+1)$
$I_2=\displaystyle\int_0^2\ln x\,\mathrm dx=2(\ln2-1)$
$I_3=\displaystyle\lim_{a\to\infty}\int_{-a}^a\frac{\mathrm dx}{x^2+1}=\pi$

Now,

$\sqrt2\approx1.4\implies \sqrt2+1\approx2.4$
$\implies \left\lceil I_1\right\rceil=2$

$e$
$\implies\left\lfloor I_2\right\rfloor=-1$

$\pi\approx3.14\implies\left\lceil I_3\right\rceil=4$

So the given equation reduces to

$\displaystyle\sum_{k=-1}^2\frac{\mathrm d}{\mathrm dx}x^{k+2}=1-4!$
$\dfrac{\mathrm dx}{\mathrm dx}+\dfrac{\mathrm dx^2}{\mathrm dx}+\dfrac{\mathrm dx^3}{\mathrm dx}+\dfrac{\mathrm dx^4}{\mathrm dx}=-23$
$4x^3+3x^2+2x+24=0$

a fairly standard cubic. Incidentally, when $x=-2$ , the LHS reduces to 0, so $x+2$ is a factor of the cubic. You can find the remaining two solutions easily with the quadratic formula.

Please help with geometry homework ! Mark brainliest

REY [17]

Theorem: If two chords intersect within a circle, then the product of the lengths of the segments (parts) of one chord is equal to the product of the lengths of the segments of the other chord.

In your case this theorem sounds as

$2\cdot x=3\cdot 6.$

Solve this equation:

$x=\dfrac{3\cdot 6}{2}=9.$

Answer: correct choice is C.

Four members of a tennis team equally shared 2 granola bars at the end of practice. how much of a granola bar did they get?

Rama09 [41]

4 divided by 2 is 2. So, 1/2 of one bar goes to each player.
