Answer:

NF = 16

Step-by-step explanation:

Since N is the incenter of ΔABC then ND = NE = NF

ND = NE ⇔ 6x - 2 = 3x + 7 ⇔ 6x - 3x = 7 + 2 ⇔ 3x = 9 ⇔ x = 3

Now , we calculate ND:

ND = 6(3) - 2 = 18 - 2 = 16

and because NF = ND then NF is also equal to 16

Anyone know the answer to this?

Lunna [17]

93 x 2 = 186

x = 186 - 112
x = 74

y = 2(80) - 74
y = 160 -74
y = 86

360 - 112 - 74 - 86 = 88
z = (88+86)/2
z = 87

Simplify completely x^2+4x-5/5x^2-8x+3

arlik [135]

Answer:

$\boxed{\bold{\frac{x+5}{5x-3}}}$

Explanation:

[ Step One ] Factor $\bold{x^2+4x-5}$

$\bold{x\left(x-1\right)+5\left(x-1\right)}$

[ Step Two ] Rewrite Equation

$\bold{\frac{\left(x-1\right)\left(x+5\right)}{5x^2-8x+3}}$

[ Step Three ] Factor $\bold{5x^2-8x+3}$

$\bold{\left(x-1\right)\left(x+5\right)}$

[ Step Four ] Rewrite Equation

$\bold{\frac{\left(x-1\right)\left(x+5\right)}{\left(5x-3\right)\left(x-1\right)}}$

[ Step Five ] Cancel Out Common Factor $\bold{x-1}$

$\bold{\frac{x+5}{5x-3}}$

$\boxed{\bold{Mordancy}}$

PLSS HELP ILL GIVE YOU BRAINLIEST!!

uysha [10]

Answer:

Step-by-step explanation:

Q1)

Use Phythogoras theorem:

$(AC)^2=(BC)^2+(AB)^2\\BC^2=AC^2-AB^2\\BC^2=6^2-4^2\\BC^2=36-16\\BC^2=20\\\\Apply\ square\ on\ both\ sides\\\\\sqrt{BC^2}=\sqrt{20} \\BC=\sqrt{20} \\BC=\sqrt{10(2)} \\BC=\sqrt{5(2)(2)} \\BC=2\sqrt{5}$

Q2)

Apply phythogoras theorem:

$CD^2=CE^2+DE^2\\CD^2=7^2+9^2\\CD^2=49+81\\CD^2=130\\\\Apply\ square\ root\ on\ both\ sides\\\\\\sqrt{CD^2} = \sqrt{130} \\\\CD=\sqrt{130} \\\\CD=11.4$

Q3)

Apply phythogoras theorem again:

$BC^2=BD^2+CD^2\\BC^2=7^2+13^2\\BC^2=49+169\\BC^2=218\\\\Apply\ square\ root\ on\ both\ sides\\\\\\sqrt{BC^2} =\sqrt{218} \\\\BC=\sqrt{218} \\\\BC=14.76$

I have an attached an image for Question 2 for better understanding the length of DE in question equals 15 - 6 = 9

How much longer is the hypotenuse of the triangle than its shorter leg?

Nastasia [14]

We can use the Pythagorean Theorem to solve for side AB
a^2+b^2=c^2
a will be 6 and b will be 8 becuase those are the legs

6^2+8^2=c^2
36+64=c^2
100=c^2 (square root both sides)
c=10

Then we find the difference between 10 and 6 because 6 is the shortest leg
10-6=4 ft. so B

Hope this helps
