Answer:
x ≥ 250
Step-by-step explanation:
Note that "greater than or equal to" looks like ≥
50 + x ≥ 300
Isolate the variable. What you do to one side, you do to the other. Subtract 50 from both sides.
x + 50 (-50) ≥ 300 (-50)
x ≥ 300 - 50
x ≥ 250
x ≥ 250 is your answer.

Answer:
A = 4 in²
Step-by-step explanation:
Given 2 similar figures with sides in ratio a : b , then
ratio of areas = a² : b²
here ratio of sides = 3.5 : 14 = 1 : 4 , then
ratio of areas = 1² : 4² = 1 : 16
That is the area of the larger pentagon is 16 times the area of smaller , so
area of smaller A = 64 ÷ 16 = 4 in²
