Let the width be x feet.

length = 2x + 3 feet

Perimeter = 2x + 2(2x + 3) = 128

6x + 6 = 128

6x = 122

x = 20 1/3

width = 20 1/3 Answer

Length = 2(20 1/3) + 3 = 43 2/3 feet Answer

Write the quadratic equation in general quadratic form below. 17x² = 12x

marusya05 [52]

Answer:

17x² - 12x + 0 = 0

Step-by-step explanation:

We can move all the terms to the same side of the equation first:

17x²=12x

17x² - 12x = 0

We know that a standard quadratic equation is in the form ax² + bx + c = 0, so we can substitute our values into this equation to match its form.

a=17

b=12

c=0

17x² - 12x + 0 = 0

Where will her cut be located? Round to the nearest tenth. x = (StartFraction m Over m + n EndFraction) (x 2 minus x 1) + x 1 A

Answer:

The correct answer is 25.2 in.

Step-by-step explanation:

It is given that number line goes from 0 to 60 which can be used to represent a ribbon of length = 60 inches.

2 inches of the ribbon are frayed so actual length = 58 inches

Please refer to the attached image for the ribbon.

A is at 0

C is at 60

B is at 2

P is the point to divide the remaining ribbon in the ratio 2:3.

Part AB of the ribbon is frayed.

BP: PC = 2:3

Let BP = 2 $x$ and PC = 3 $x$

Now, BP + PC = BC = 58 = 2 $x$ + 3 $x$ = 5 $x$

So,

$5x =58\\\Rightarrow x =11.6$

BP = $2\times x = 2 \times 11.6 = 23.2\ inches$

Location of the Cut = 2 + 23.2 = 25.2 inches

Alternatively, we can use the formula directly:

$x = \dfrac{m} {m + n } (x_2 - x_1) + x_1$

$x_1 = 2\\x_2 = 60$

m: n is the ratio 2:3

$x = \dfrac{2} {2 +3 } (60- 2) + 2\\\Rightarrow 0.4 (58 )+2\\\Rightarrow 23.2+2 \\\Rightarrow \bold{25.2\ inches}$
