The area of a square is represented by the expression 16x^4y^8. What is the length of each side of this square

Leona [35]

Answer: $4x^2y^4$

Step-by-step explanation:

Given

The area of the square is $A=16x^4y^8$

Suppose a is the side length of the square

The area of the square is given by

$\Rightarrow A=(\text{side length})^2$

So, we can write

$\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4$

length of each side is $4x^2y^4$

I’m kinda confused. Can someone help.

horsena [70]

Answer:

PQ = $PM\cos MPQ + MQ\cos MQP=2PM\cos MQP$

Step-by-step explanation:

given MQR = 60, PQR = 75

MQP = 75 -60= 15 $QR = ((18(1+\cos 30))^{2}-(2\cos 15)^{2})^{\frac{1}{2}}$

WE KNOW THAT MQR +QRM +QMR = 180

MPQ = MQP AS ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL

THEREFORE QMR = 90 - 60 = 30

therefore PQM = 75 - 60 = 15

PM = PQ because M is the mid point

therefore PR = PM + $MQ\cos QMR$

PR = $18(1+\cos 30)$

$QR = (PR^{2}-PQ^{2}))^{\frac{1}{2}}$

PQ = $PM\cos MPQ + MQ\cos MQP=2PM\cos MQP$
