Answer:
To evaluate a variable expression means to find the value of the expression for given values of the variables. To evaluate, substitute the given values for the variables in the expression and simplify using the order of operations (PEMDAS).
Step-by-step explanation:
3230 kilograms of the soil supplement are required for the entire vineyard
<h3>Further explanation</h3>
Some units that need to be recalled are as follows :
<em>1 km = 1000 m = 10³ m</em>
<em>1 km² = 1000000 m² = 10⁶ m</em>
<em>1 km² = 247 acres</em>
<em>1 kg = 1000 g</em>
Let's tackle the problem now!
A vineyard has 145 acres of Chardonnay grapes.
A particular soil supplement requires 5.50 grams for every square meter of vineyard.
<h2>Conclusion :</h2>
It required 797500/247 kg ≈ 3230 kg of the soil supplement for the entire vineyard

Step-by-step explanation:
We determined above that the greatest perfect square from the list of all factors of 96 is 16.
Answer:
Step-by-step explanation:
Width =w
Length = 2w + 3
Perimeter = 2*(length +width)
= 2*(2w +3 + w )
= 2*(3w + 3)
= 6w + 6
b) Perimeter = 30 units
6w + 6 = 30
Subtract 6 form both sides
6w = 30- 6
6w = 24
Divide both sides by 6
6w/6 = 24/6
w = 4
l = 2w + 3
= 2*4 + 3
= 8 + 3
= 11
Length = 11 units
Width = 4 units
