Answer: n=1
the answers would have to be less than 3 so you subtract 2–1 and you get one and one is less than 3

Hope this helps:) !!

n is equal to :

2-1 = 1 so n would have to be 1 in order to be less than 3

The perimeter of XYZ is ___ units.

In-s [12.5K]

Look at the picture.

$ZY = 5+3=8$

For XY and ZX use the Pythagorean theorem.

$XY^2=3^2+4^2\\\\XY^2=9+16\\\\XY^2=25\to XY=\sqrt{25}\\\\XY=5$

$ZX^2=5^2+4^2\\\\ZX^2=25+16\\\\ZX^2=41\to ZX=\sqrt{41}$

The perimetero fo XYZ:

$P_{\triangle XYZ}=8+5+\sqrt{41}=\boxed{13+\sqrt{41}}$

If a bottle rotates through 270 degrees in 3 seconds how many degrees does it rotate in 2 seconds

abruzzese [7]

The bottle rotates 180 degrees in 2 seconds.

I divided 270 by 3, which was 90. Then, I multiplied 90 by 2. Which was 180.<span />

Find the area of a triangle who's side lengths are 13, 14, and 15. (The questions doesn't tell the type of triangle.)

Y_Kistochka [10]

Answer:

84 square units.

Step-by-step explanation:

<h2>Area of scalene triangle:</h2>

$\sf \boxed{\bf Area = \sqrt{s*(s-a)(s-b)*(s-c)}}$

Here, a, b and c are the sides of the triangle. s is the semi perimeter.

a = 13

b = 14

c = 15

$\sf s= \dfrac{a+b+c}{2}\\\\ =\dfrac{13+14+15}{2}\\\\=\dfrac{42}{2}\\\\s = 21$

s -a = 21 - 13 = 8

s -b = 21 - 14 = 7

s - c = 21 - 15 = 6

$\sf Area = \sqrt{21*8*7*6}$

$= \sqrt{ 7* 3 * 2 * 2 * 2 * 7 * 2 * 3}\\\\=7 * 3 *2*2\\\\= 84 \ square \ units$

Use the quadratic formula to solve 5x^2+2x-3

Lisa [10]

Assuming it equals 0
for
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$

given
5x^2+2x-3=0
a=5
b=2
c=-3

x= $\frac{-2+/- \sqrt{2^2-4(5)(-3)} }{2(5)}$
x= $\frac{-2+/- \sqrt{4+60} }{10}$
x= $\frac{-2+/- \sqrt{64} }{10}$
x= $\frac{-2+/- 8 }{10}$
x=(-2+8)/10 or (-2-8)/10
x=6/10 or -10/10
x=3/5 or -1
