Answer:

$x=\frac{1}{4}$

Step-by-step explanation:

$81^{x+1}+3^{4x}=246$

$81=3^4$

Rewrite equation: $3^{4\left(x+1\right)}+3^{4x}=246$

$3^{4\left(x+1\right)}=3^{4x}\times 3^4$

$3^{4x}\times 3^4+3^{4x}=246$

Factor out $3^{4x}$ :

$3^{4x}\left(3^4+1\right)=246$

Divide both sides by $(3^4+1)$ :

$\frac{3^{4x}\left(3^4+1\right)}{3^4+1}=\frac{246}{3^4+1}$

$3^{4x}=\frac{246}{3^4+1}$

$3^{4x}=\frac{246}{82}$

$3^{4x}=3$

Anything to the power of 1 is itself. Hence,

$4x=1\\$

$x=\frac{1}{4}$

You are planning to make a collage and are gathering materials.for the backing you will use a piece of heavy recycled cardboard

1. 4 3/4 feet = 19/4 feet
2 2/5 feet=12/5 feet.
multiplying them together yields
$\frac{19}{4} * \frac{12}{5} =$
$= \frac{57}{5} = 11.4 ft^{2}$

Part 2:
11.4 ft^2 - 4 1/2 ft^2=
11.4-4.5=6.9 ft^2 = 69/10 ft^2 left after you subtract the decoration in the middle
Now you're trying to find now many rectangular cutouts (that each are 3/8 ft^2) will fit in the remaining space.
You do that by dividing the remaining space left by 3/8:
$\frac{69}{10} / \frac{3}{8} = \frac{69}{10} * \frac{8}{3} = \frac{92}{5}$
since you have to have a whole number of cutouts, you round 92/5 down to 90/5, which is 18 cutouts

Will give brainliest

klemol [59]

Your question is calling the figure ABCD, but the image is showing PQRS

Using the letters that you wrote:

Because the figure was only rotated and not scaled , the sides with the same letters would still be the same

So AB would be the same as A'B' ( Length of AB = Length of A′B)

and

BC = B'C'

CD = C'D'

AD = A'D'

Or by the picture:

PQ = P'Q'

QR = Q'R'

RS = R'S'

PS = P'S'
