Choose the true biconditional statement that can be formed from the conditional statement "If the area of a square is 25 square meters, then the
side length of the square is 5 meters" and its converse.
A. If the side length of a square is not 5 meters, then the area of the
square is not 25 square meters.
O B. A biconditional cannot be formed because the statement and its
converse are not logically equivalent.
C. The area of a square is 25 square meters if and only if the side
length of the square is 5 meters.
O D. The side length of a square is 5 meters if and only if the area of
the square is not 25 square meters.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

i believe the answer is 323 ft

step-by-step explanation:

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
