PEMDAS is very helpful. Without pemdas, people solve equations differently. For example, 2 + 3 * 2. Using pemdas, we knoow 2 + 3 * 2 = 8
However, without pemdas, someone could do 2 + 3, which is 5, then *2. Which would get 10.
PEMDAS is important to keep order.
For f(x)=1/x^2-3
Find
A) f(3)
B) f(2-h)
If f(x)=1/x^2-3, then f(3) = 1 / 3^2 - 3. The exponentiation here must be carried out first: f(3) = 1/9 - 3. Then f(3) = 1/9 - 27/9 = -26/9
If f(x)=1/x^2-3, then f(2-h) = 1 / [2-h]^2 - 3. This result may be left as is or expanded. In expanded form, we have:
1
f(2-h) = ------------------ - 3
4-4h +h^2
b or the second option
The correct answer for the question that is being presented above is this one: "w(w + 2) = 48." John has 48 square centimeter tiles he wants to use to create a mosaic. He wants the mosaic to be rectangular with a length that is 2 centimeters longer than the width.
Let w = width
Let (w+2) = length
Area = w(w+2).
Answer:
-8 • (6 + 3) + 390 + 6=324
Step-by-step explanation:
we know that
1 gal.= 3.8L
we can also write as
3.8L=1 gal
Firstly, we will find for 1L
so, we can divide both sides by 3.8
now, we will multiply both sides by 22
so, option-b.............Answer
