Lets get started :)
We need to isolate t from x =
at²
Take 2 to the left-hand side { Do multiplication since you see division }
2x = at²
Take a to the left-hand side { Do division since you see multiplication }
= t²
Take square root since t is to the power of 2
= t

Answer:
The length of each of the other two sides would be 3.1 cm
Step-by-step explanation:
<u><em>The options of the question are</em></u>
A. 3.1 cm
B. 3.2 cm
C. 4.2 cm
D. 6.1 cm
we know that
An isosceles triangle has two equal sides and two equal interior angles
Let
x -----> the length of each of the two equal sides in the isosceles triangle
The perimeter of one isosceles triangle is equal to
Remember that
To maximize the use of the wire, the perimeter of 6 earrings (3 pairs of earrings) must be equal to 50 cm
so
Solve for x
therefore
The length of each of the other two sides would be 3.1 cm
