Answer:

x = 65

Step-by-step explanation:

using the Altitude- on- Hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)

x² = 25 × 169 = 4225 ( take square root of both sides )

x = $\sqrt{4225}$ = 65

Given parameters:

Total length of curtains bought = 20m

She used 8m for the living room

She used 7m for the dining room

unknown:

Quantity used for the kitchen = ?

Solution:

Quantity used for the kitchen = Total length - (living room + dining room)

Input the parameters given solve;

Quantity used for the kitchen = 20 - (8 + 7) = 5m

The length of curtain used for the kitchen is 5m

Use the quadratic formula to find the solutions for<br> y = 3x^3 + 8x - 1

mote1985 [20]

Answer:

Solving the equation using quadratic formula we get $\mathbf{x=0.119\:or\:x=-2.785}$

Step-by-step explanation:

We need to use the quadratic formula to find the solutions for

$y = 3x^2 + 8x - 1$

<em>(Note: quadratic formula is used when x^2 is in the equation. So considering 3x^2 instead of 3x^3)</em>

The quadratic formula is: $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

From the given equation $y = 3x^3 + 8x - 1$ we have a =3, b=8 and c =-1

Putting values in the formula and finding solutions:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-8\pm\sqrt{(8)^2-4(3)(-1)}}{2(3)}\\x=\frac{-8\pm\sqrt{64+12}}{6}\\x=\frac{-8\pm\sqrt{76}}{6}\\x=\frac{-8\pm8.71}{6}\\x=\frac{-8+8.71}{6}\:or\:x=\frac{-8-8.71}{6}\\x=0.119\:or\:x=-2.785$

So, Solving the equation using quadratic formula we get $\mathbf{x=0.119\:or\:x=-2.785}$
