Sammy is classifying quadrilateral EFGH. How can she use coordinate geometry to determine whether EFGH is a rhombus?
E(2,5). F(1.3). G(2.1). H(3.3)
Sammy can use the distance formula to show that the opposite sides have equal slopes.
Sammy can use the distance formula to show that all sides are equal
Sammy can use the slope formula to show that the opposite sides have equal slopes
Sammy can use the slope formula to show that all sides are equal.

B

Step-by-step explanation:

Rhombus has all sides equal  

it’s the first one your welcome

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
