The correct answer is C. (5x+3) feet, and here is how I got it.
This is the equation you need to use:
(a+b)^2 = (a+b) (a+b)
So, let us plug in 5x and 3 here:
(5x+3)^2 = (5x+3)(5x+3) = 25x^2 + 15x + 15x + 9 = 25x^2 + 30x + 9 which is the area of the garden.
Answer:
Complementary angle
Step-by-step explanation:
It adds up to 90 degrees
Answer:
3
Step-by-step explanation:
Since + × - = -
The - sign will change
+7 - 4 = 3
First, find the area of the reptile room and the aquarium. A=l*w=72*83=5,976
Second, find the area of ONLY the reptile room. A=l*w. l=72-52=20 w=83-32=51
A=20*51=1,020
Third, find the area of the Amphibian room and the aquarium. A=l*w=72*83=5,976
Fourth, subtract the area of the reptile room from the area of the Amphibian room. 5, 976 - 1,020=4,956=Amphibian room area.
Fifth, add the area of the amphibian room to the area of the reptile room and the aquarium.
4,956+5,976=10,932 ft^2 is the total area of both rooms and the aquarium.
