for the other question u can use calculator :)
Answer:
i'm sorry i think math is too hard could u help me
Step-by-step explanation: i understand the math problem
Answer:
5+n
you have to distribute the “+” so you can drop the parenthesis. Then, you have 3+2+n. Add and you end up with 5+n
The side that measures 12 cm corresponds to the side that measures 3 cm.
The side that measures 16 cm corresponds to the side that measures 4 cm.
The ratio of the side lengths is (12 cm)/(3 cm) = (16 cm)/(4 cm) = 4
Now let's calculate the two areas.
For the 3 cm by 4 cm rectangle:
A = LW = 3 cm * 4 cm = 12 cm^2
For the 12 cm by 16 cm rectangle:
A = LW = 12 cm * 16 cm = 192 cm^2
The ratio of the areas is (192 cm^2)/(12 cm^2) = 16
The ratio of the areas is 16.
The ratio of side lengths is 4.
Notice that 16 = 4^2.
The ratio of the areas is the square of the ratio of the side lengths.
