Answer:
200
Step-by-step explanation:
46
When it says f(4) that means x=4
So you then just fill in all the x’s with 4’s and solve as normal
Answer: 100 square units.
Step-by-step explanation:
Given: Jernel has to figure out the area of her square garage.
She knows that one side of the garage is equal to the length of her rabbit pen.
Now, the length of the rabbit pen = 10 units
Then , the length of the garage will be 10 units
Now, Area of square = 
Hence, the area of the garage = 100 square units.
I=PRT/100
1. Make R (rate) subject
R/100= I/PT
2. Substitute and calculate
r/100= i/pt
r/100= 40/400 × 1
(<em>4</em><em>0</em><em> </em><em>i</em><em>s</em><em> </em>from 440-400.<em>T</em><em>h</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>e</em><em>r</em><em>e</em><em>s</em><em>t</em>)
r/100= 0.1
r/100×100= 0.1×100
r=10% (interest rate per year)
To confirm
I=PRT
I= 400×10/100×1
I= $40 (Interest)
