BRAINLIEST ASAP!<br><br><br>Solve for n: –6 (n–8) = 4 (12–5n) + 14n.
Alisiya [41]

Answer:

ℝ

Explanation:

–6(n – 8) = 4(12 – 5n) + 14n

–6n + 48 = 48 – 20n + 14n

–6n + 48 = 48 – 6n ☑

These two expressions are EXACTLY the same, therefore <em>all</em><em> </em><em>real</em><em> </em><em>numbers</em><em> </em>of <em>n</em><em> </em>would make this equation true.

I am joyous to assist you anytime.

That would be  a / 3b^2

A line passes through the point (–2, 7) and has a slope of –5. What is the value of a if the point (a, 2) is also on the line?
never [62]
(x1,y1) = (-2,7)
m = -5
(x,y) = (a,2)

Forming the equation,
(y-y1) = m(x-x1)
y - 7 = -5[x - (-2)]
y - 7 = -5x - 10
y + 5x = -3

Putting the values of (x,y) we get,
2 + 5a = -3
5a = -5
a = -1

Help...please?? Thanks guys
vfiekz [6]

Answer:

x=20

Step-by-step explanation:

The Pythagorean theorem is

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse.

The legs are x and 15 and the hypotenuse is 25

x^2 + 15^2 = 25^2

x^2 +225 = 625

Subtract 225 from each side

x^2 +225-225 = 625-225

x^2 = 400

Take the square root of each side

sqrt(x^2) = sqrt(400)

x = 20
