Answer:

a. f(2) = 6

b. f(3) + f(-3) = 62

d. 3(x+1)^2 - 5(x+1) + 4

e. This one looks like the secant line equation. Not fully sure.

Step-by-step explanation:

You replace whatever is inside of the parenthesis with the x in the function. For the first two, you just have to calcluate the numbers.

IF S.P. = Rs 1,869, loss percent = 11% find C.P.

Veseljchak [2.6K]

Here,

Selling Price (S.P) = Rs 1869

Loss = 11%

Cost Price (C.P) = ?

Let, C.P be x

Now,

Sp = Cp - loss% of Cp

1869 = x - 11/100*x

1869 = (100x - 11x)/100

186900 = 89x

◆ x = Rs 2100

Cp = Rs 2100

I hope you understand...

It's a Right answer...

Thanks♥♥

Match the width with the go given area.

LekaFEV [45]

Hello!

<h2>Answer:</h2>

$\boxed{ \bf 1.~l~=~9.25~cm;~A~=~55.5~cm^2~matches~with~the~last~option~w~=~6~cm.}$

$\boxed{ \bf 2.~l~=~7.5~cm;~A~=~48.75~cm^2~matches~with~the~second~option~w~=~6.5~cm.}$

$\boxed{ \bf 3.~l~=~5~cm;~A~=~44~cm^2~matches~with~the~third~option~w~=~8.8~cm.}$

$\boxed{ \bf 4.~l~=~5~cm;~A~=~31.25~cm^2~matches~with~the~first~option~w~=~6.25~cm.}$

<h2>__________________________________</h2><h2>Explanation:</h2>

We already know that the formula for area of a rectangle is A = l × w.

Notice how the width and the length are being multiplied to find the area.

Well, to find the width, we must do the <em>opposite</em> of multiplication, which is division.

Since we already have the length, all we have to do is divide the area by the length for each of the questions.

A = l × w

55.5 = 9.25 × w

$\frac{55.5}{9.25}$ = 6

A = l × w

48.75 = 7.5 × w

$\frac{48.75}{7.5}$ = 6.5

A = l × w

44 = 5 × w

$\frac{44}{5}$ = 8.8

A = l × w

31.25 = 5 × w

$\frac{31.25}{5}$ = 6.25
