What is the last one number 12

What is the simplified form of this expression?<br> (3 - 13x - 7x?) - (5X2 + 12x - 10)

tatiyna

Answer:

-5x^2-32x+13

Step-by-step explanation:

(3-13x-7x)-(5x^2+12x-10)

3-20x-5x^2-12x+10

-5x^2-32x+13

Erin already has 7 plants in her backyard, and she can also grow 2 plants with every seed

Reil [10]

The answer is p=2s+7. Two plants can be grown from each seed packet, and Erin already has seven plants so you add that to the equation as well.

1. Parallelogram ABCD is similar to

ss7ja [257]

Answer:

The length of GH is 2 inches

Step-by-step explanation:

The given parameters are;

Parallelogram ABCD ~ Parallelogram EFGH

Segment BC of parallelogram ABCD corresponds to segment FG of parallelogram EFGH

Similarly

Segment CD of parallelogram ABCD corresponds to segment GH of parallelogram EFGH

In parallelogram ABCD, we have;

Segment BC = 21 in.

Segment CD = 6 in.

In parallelogram ABCD, we have;

Segment FG = 7 in.

Given that parallelogram ABCD is similar to parallelogram EFGH, we have;

$\dfrac{\overline{BC}}{\overline{FG}} = \dfrac{\overline{CD}}{\overline{GH}}$

Which by substitution, gives;

$\dfrac{21}{7} = 3 = \dfrac{6}{\overline{GH}}$

$\therefore \overline{GH} = \dfrac{6}{3} = 2$

$\overline{GH}$ = 2 inches

Use the divergence theorem to calculate the surface integral ??s f · ds; that is, calculate the flux of f across s. f(x,y,z = ex

Kamila [148]

$\mathbf f(x,y,z)=e^x\sin y\,\mathbf i+e^x\cos y\,\mathbf j+yz^2\,\mathbf k$

By the divergence theorem, the surface integral can be evaluated by computing the triple integral

$\displaystyle\iint_Sf(x,y,z)\,\mathrm dS=\iiint_V\nabla\cdot\mathbf f(x,y,z)\,\mathrm dV$
$=\displaystyle\iiint_V\left(\dfrac{\mathrm d\mathbf f}{\mathrm dx}+\dfrac{\mathrm d\mathbf f}{\mathrm dy}+\dfrac{\mathrm d\mathbf f}{\mathrm dz}\right)\,\mathrm dV$
$=\displaystyle\int_{x=0}^{x=4}\int_{y=0}^{y=3}\int_{z=0}^{z=4}2yz\,\mathrm dz\,\mathrm dy\,\mathrm dx$
$=72$

A friend asks to borrow $250 for 120 days and agrees to pay 2.5% simple interest every 30 days. How much interest will you earn

IgorC [24]

Answer:

We will $ 6.25 of interest every 30 days.

Step-by-step explanation:

Please notice that a month equals 30 days and that earning due to interests will be only effective after each 30th day. The simple interest formula is defined by the following formula:

$I = \frac{C\cdot r\cdot t}{100}$ (1)
