Find the area of the room by multiplying the length by the width:
Area of room = 20 x 12 = 240 square feet.
Find the area of the tile: 2x 2 = 4 square feet.
To find the number of tiles divide the area of the room by the area of a tile:
240/4 = 60
They will need 60 tiles.
Answer:
x = 52
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ PQS is an external angle of the triangle, thus
x + 72 = 90 + 34 = 124 ( subtract 72 from both sides )
x = 52
Answer:
2x+13
Step-by-step explanation:
Plug in (x+3) in the F(x) function so:
f(x+3) = 2(x+3) + 7 = 2x+6+7 =2x+13
ANSWER: F(x+3) = 2x+13
