Answer: 4x4=16, 6x6x6x6=1296, 1296+16=1312
the answer is 1312
Step-by-step explanation: find the area. 4x4, 6x6x6x6, the 3 is only there to throw you off you dont do anything with the 3
i think thats right
Let's solve your system by substitution.
2x−2y=−4;2x+y=11
Rewrite equations:
2x+y=11;2x−2y=−4
Step: Solve2x+y=11for y:
2x+y=11
2x+y+−2x=11+−2x(Add -2x to both sides)
y=−2x+11
Step: Substitute−2x+11foryin2x−2y=−4:
2x−2y=−4
2x−2(−2x+11)=−4
6x−22=−4(Simplify both sides of the equation)
6x−22+22=−4+22(Add 22 to both sides)
6x=18
6x/6 = 18/6
(Divide both sides by 6)
x=3
Step: Substitute3forxiny=−2x+11:
y=−2x+11
y=(−2)(3)+11
y=5(Simplify both sides of the equation)
Answer:
x=3 and y=5
The area of one tile is 18 x 18 = 324 square inches.
Convert the dimensions of the room into inches:
5 ft 6 in. = 66 inches.
13 ft = 156 inches.
The area of the room is: 156 x 66 = 10296 square inches.
To find the number of tiles needed, divide the total area of the room by the area of one tile:
10,296 / 324 = 31.78, which means they will need 32 tiles.
