Answer:
Possible values of x are 50 < x < 110.
Step-by-step explanation:
Consider the perimeter of the field:
2x + 2(x + 30) < 500
2x + 2x + 60 < 500
4x < 440
x < 110.
Consider the area of the field:
x(x + 30 ) > 4000
x^2 + 30x - 4000 > 0
(x - 50)(x + 80) > 0
The critical values are x = -80 and 50.
As x is a width it must be positive so x > 50.
Answer:
a geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-one number called the common ratio. hope this helped :)

Answer:
690
Step-by-step explanation:
Round from the tens place.
Answer:
m ≤ - 10
Step-by-step explanation:
m/-5 ≥ 2
Multiply both sides by -5 to isolate m. Because we are multiplying by a negative, we must flip the sign.
m ≤ -10
<span>Simplifying
4x + 5y = 11
Solving
4x + 5y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
4x + 5y + -5y = 11 + -5y
Combine like terms: 5y + -5y = 0
4x + 0 = 11 + -5y
4x = 11 + -5y
Divide each side by '4'.
x = 2.75 + -1.25y
Simplifying
x = 2.75 + -1.25y</span>
