What expression in terms of x can be used to represent the area of parallelogram PQRS?

borishaifa [10]

Answer:

C. (5x√2)² = 50x²

Step-by-step explanation:

Area of parallelogram = QR²

QR = √((5x)² + (5x)²) ---› pythagorean theorem

QR = √(25x² + 25x²) =

QR = √(50x²)

QR = √(25*2*x²)

QR = 5x√2

✔️Area of parallelogram = QR²

= (5x√2)² = 25x² × 2 = 50x²

Se van a unir dos tramos de cadena: uno mide 0.75 m de largo y el otro 15/100 de metro . ¿Cual será la longitud total ya que est

likoan [24]

Step-by-step explanation:

It is given that,

The length of section 1 is 0.75 m and the length of section 2 is 15/100 m. The total length of the section is equal to the sum of section 1 and section 2. So, we will add them as follows :

$l=0.75\ m+\dfrac{15}{100}\ m\\\\\because \dfrac{15}{100}=0.15\\\\l=0.75\ m +0.15\ m\\\\l=0.9\ m$
