Mathematics

Degger [83]3 years ago

Let the length be x

Area = x²
Perimeter = 4x

<span>Area of a square is 3 times its perimeter
</span>⇒ x² = 3(4x)

x² = 3(4x)
x² = 12x
x² - 12x = 0
x(x - 12) = 0
x = 0 or x = 12

Since x cannot be zero, x = 12

Answer: The length is 12 units.

Which equation can be used to find the solution of (1/4)^y+1=64?
Ne4ueva [31]

Answer:

−y−1=3

Step-by-step explanation:

Which equation can be used to find the solution of (1/4)^y+1=64?

This can be solved by power of indices

(1/4)^(y+1)=64

(4^-1)^(y + 1)= 4^3

Note

(x^a)^b = x^ab

Hence:

4^(-1)(y + 1)= 4^3

4^-y - 1 = 4^3

Divide both sides by 4

−y−1=3

Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is

−y−1=3
