First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x

Now you may subtract those two

7-4x= 3x

9/(x - 8) = 4/5 how to solve this proportion

ICE Princess25 [194]

$\frac{9}{x-8}=\frac{4}{5}$
Cross multiply:
$(9)(5)=(4)(x-8)$
Simplify:
$45=4x-32$
Group like terms:
$77=4x$
Solve for x by division:
$x=\frac{77}{4}$
$x=19.25$

The width of a golden rectangle is 15 feet. Find the perimeter of the rectangle to the nearest foot.

topjm [15]

Answer:

79 ft

Step-by-step explanation:

Golden rectangle side ratios 1 : (1+sqrt5 )/2

(approx 1: 1.618)

15 + 15 + 2*15*1.618 = <u>~79 ft </u>

BUT perhaps the 15 is the 1.618 side

15/1.618 + 15/1.618 + 15 + 15 ~ 49 feet
