Answer: y=55 x=6

Step-by-step explanation: Because of the two equivalent lines in lines DE and FE we know that the angles D and F must be equal, therefore y is 55. And now we know that angles D and F add up to 110 and because all of the angles in a triangle add up to 180, angle E must equal 70.

Angle E- (11x+4)=70

-4 -4

11x=66

divide both sides by 11

x=6

1. Given that (27 ^ (n + 3))/(81 ^ (p - 1)) = 3 , express p in terms of h.

Answer:

p = 3/4n +3

Step-by-step explanation:

Expressing the given equation in terms of powers of 3, we have ...

(27^(n+3))/(81^(p-1)) = 3

(3^3)^(n+3)/(3^4)^(p-1) = 3^1 . . . . as powers of 3

3(n +3) -4(p -1) = 1 . . . . . . . . . . . . log base 3 (or, equate exponents)

3n +9 -4p +4 = 1 . . . . . . . . . . . . . eliminate parentheses

3n +12 = 4p . . . . . . . . . . . . . . . . add 4p -1

p = 3/4n +3 . . . . . . . . . . divide by 4

What two numbers add up to 6 and multiply to 12?

GuDViN [60]

Erm

x+y=6
xy=12

x+y=6
y=6-x
sub back

xy=12
x(6-x)=12
6x-x^2=12
x^2-6x=-12
x^2-6x+12=0
quadratic formula
for
ax²+bx+c=0
$x= \frac{-b+/- \sqrt{b^2-4ac} }{2a}$

for
x²-6x+12=0
a=1
b=-6
c=12
and remember that √-1=i

$x= \frac{-(-6)+/- \sqrt{(-6)^2-4(1)(12)} }{2(1)}$
$x= \frac{6+/- \sqrt{36-48} }{2}$
$x= \frac{6+/- \sqrt{-12} }{2}$
$x= \frac{6+/- (\sqrt{-1})(\sqrt{12}) }{2}$
$x= \frac{6+/- (i)(2\sqrt{3}) }{2}$
$x= \frac{6+/- 2i\sqrt{3} }{2}$
x=3+/-i√3

the numbers are 3+i√3 and 3-i√3
no real numbers tho
