Find the remainder when f(x) = x3 − 14x2 51x − 22 is divided by x − 7.

Answers

We can use at least two approaches in answering this question. But the easiest way is to use the $<b>Remainder Theorem</b>$

According to the Remainder Theorem, if
$(x - a)$
is not a factor of
$f(x)$
then evaluating the function at
$x = a$
gives us the Remainder when
$f(x)$
is divided by
$(x - a)$
That is
$f(a) = R$

For the given question, we have

$f(x) = {x}^(3) - 14 {x}^(2) + 51x - 22$
When this function is divided by
$x - 7$
The remainder is given by
$f(7) = R$
$f(7) = {7}^(3) - 14( {7})^(2) + 51(7) - 22$
$f(7) = 343 - 14( 49) + 51(7) - 22$
$f(7) = 343 - 686+ 357 - 22$
$f(7) = - 8$
$<b>Hence the remainder is -8</b>$

The remainder is -8.

Please solve the problem.

OK. I did it, and I have the solution.

The length of the deck is (5 + 2x) .
The width of the deck is   (4 + 2x) .

If the deck didn't have that big hole in the middle where the pool is,
then its area would be

   (5 + 2x) · (4 + 2x) .

When you multiply that all out, you get    Area = 4x² + 18x + 20

and the question tells us that the area of the whole big rectangle is 90 yds² .
So we can write

   4x² + 18x + 20 = 90 .

Subtract 90 from each side:    4x² + 18x - 70 = 0
Divide each side by 2 :    2x² + 9x - 35 = 0

You can use the quadratic equation to solve that and find out that
x = 2.5 yards, and that's what the question is asking you.

That makes the deck 10 yds high and 9 yds wide.

Total area of the whole big rectangle, (deck + pool ), = 90 yds².

the area of the field is 6000 square yards. write and solve a formula to find the width of the field

Answers

Answer: For a rectangular shape, the area is equal to the product of th length and the width. so A = L*W

If the area is 6000 $yd^(2)$

so if you want to know the width you need to solve the equation W = A/L for finding the value of W.

I think in the picture says that L = 60 yds

so W = 6000/60 = 100 yards.

L-lenght
W-width

A = L·W

A = 6000 yd
L = 60 yd

subtitute

60W = 6000 |divide both sides by 60

W = 100 (yd)
