The answer is b. The Remainder<span> Theorem says that if a polynomial </span>f(x<span>) is divided by </span>x<span> – k, then </span>the remainder<span> is </span>f(k). k=3 in our case, so the remainder is simply f(3). Plug in x=3 into <span>f(x) = 7x4 + 12x3 + 6x2 - 5x + 16. f(x)=946. So the answer is b.</span>

Write the common rule to describe the translation using coordinate notation.

UNO [17]

The common rule is (x - 1, y + 3) can be used to describe the translation.

Step-by-step explanation:

Step 1:

The point J (-3, -4) becomes $J^{1}$ (-4, -1).

In order to write the rule for translation from J to $J^{1}$ , we subtract the x coordinate of J from $J^{1}$ and subtract the y coordinate of J from $J^{1}$ .

The x coordinate $= -4-(-3) = -4+3 = -1.$

The y coordinate $= -1-(-4) = -1+4 = 3.$

Step 2:

So from the calculations, we get that the x coordinate is subtracted by 1 i.e. $x-1$ and the y coordinate is increased by 3 i.e. $y+3$ .

So the common rule is (x - 1, y + 3).

4. Find the area of the rhombus.

Juliette [100K]

Answer:

The area of the rhombus is $72\ m^{2}$

Step-by-step explanation:

we know that

To find the area of a rhombus, multiply the lengths of the two diagonals and divide by 2

$A=\frac{1}{2}(6+6)(6+6)=72\ m^{2}$

Which complex number is equivalent to the given expression?<br> (-45 - 22i) + 2(5 - 3i)(5 + 3i)

PilotLPTM [1.2K]

Hint:

Use distributive property, then combine like terms.

I think you've got it from there :)

If you need more help, just comment on this.

If you still are confused, then see below.

Answer:

-45-22i+(10-15i)(5+3i)

-5-22i+50+30i-75i-45i

112i-45

iogann1982 [59]

Answer:

-x + 10

Step-by-step explanation:

$-9x^{2}$ + 4x + $9x^{2}$ + 3x + 10

Collect like terms = -1x + 10 OR -x + 10
