Please help me :(<br><br>I am in Great trouble:(​
Komok [63]

Answer: (I am not a maths moderator)

x=4

Step-by-step explanation:

Multiply the exponents

(2x-4)^12=(4^2)^6 (exponents multiply so)

(2x-4)^12=4^12

4^12 = 16777216

(2x-4)^12= 16777216

Take the 1/12 exponent for both sides

that will remove the ^12 exponent from the left side and will take the 12th root for the right.

2x-4=4

add 4 to both sides

2x=8

divide both sides by 2

x=4

C is the circumcenter of APQR.<br> PC=3x+7, RC=5x-15, &amp; QC=51-X<br> x=[?]
amm1812

Answer:

x = 11

Step-by-step explanation:

C is the circumcenter of \triangle PQR

\implies PC=QC=RC (Radii of same circle)

\implies RC=QC

\implies 5x-15=51-x

\implies 5x +x=51+15

\implies 6x =66

\implies \: x =  \frac{66}{6}  \\  \\  \implies \:  \huge \:  \red{x = 11}
