Answer:
Step-by-step explanation:
GCF: -6x^2 and 15x^3 the GCF is 3x^2
the GCF for this polynomial is 2x(16y-9x)
$810 ÷ 3 = 270 square feet
Area of the room is 270 square feet.
Area = 270 square feet, length = 18 feet
Area = Length x Width
270 = 18 x width
Width = 280 ÷ 18
Width = 15 feet
The room is 15 feet wide.

Answer:
x = 4.2 cm
Step-by-step explanation:
12.6/14.7 = x/4.9
cross-multiply to solve for 'x':
14.7x = 12.6(4.9)
14.7x = 61.74
x = 61.74÷14.7
x = 4.2
Answer:
3(25) + 5 = 80
x = 25
Step-by-step explanation:
3x + 5 + 75 + x = 180
4x + 80 = 180
4x = 100
x = 25
3x + 5
3(25) + 5 = 80
x = 25
