Answer:
A+3b+4
Step-by-step explanation:
You multiply everything by 1/2 which is like dividing it by 2
The solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have an inequality:
−14a ≥ 42
-a ≥ 3
a ≤ -3
a ∈ (-∞, -3]
Thus, the solutions to the inequality are (-∞, -3] or a ≤ -3 if the inequality −14a≥ 42 graph is shown in the picture.

Answer:
Step-by-step explanation:
Area of garden = length * breadth = 90 * 75 = 6750 Sq . m
= 6750 / 1000 = 0.675 hectare
Area of path = 100 * 85 - 90 * 75
= 8500 - 6750 = 1750 Sq. m
