Which equation is equivalent to 4^x+3 =64
A. 2^x+6 = 2^4
B. 2^2x+6 = 2^6
C. 4^2x+6 = 4^2
D. 4^x+3 = 4^6

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
