Answer:

( 7x + 11  )( 7x-  11 )

Step-by-step explanation:

( 7x + 11  )( 7x-  11 )

Because 7*7 is 49

-11*11= -121

7*11=77

-7*11= -77

77-77=0

so the answer is 49x^2-121

two similar containers have base areas 26cm² and 324cm² respectively. Calculate the capacity of the larger container correct to
Setler79 [48]

Answer:

351.9 cm³

Step-by-step explanation:

The ratio of the areas of two similar solids is equal to the square of the ratio of the lengths.

A₂ / A₁ = (s₂ / s₁)²

The ratio of the volumes of two similar solids is equal to the cube of the ratio of the lengths.

V₂ / V₁ = (s₂ / s₁)³

Therefore, we can say:

V₂ / V₁ = (A₂ / A₁)^(3/2)

Plugging in values:

V / 8 cm³ = (324 cm² / 26 cm²)^(3/2)

V = 351.9 cm³
