Answer:
14x +13
Step-by-step explanation:
4(6x+2)-5(2x-1)
Distribute
24x +8 -10x +5
Combine like terms
24x -10x +8+5
14x +13
50 cm in meters is 0.5 m
Area of a tile = 0.5 * 0.5 = 0.25 m^2
Total area to be covered = 5 * 5 = 25 m^2
Tiles required = 25/0.25 = 100
The correct answer is
The explicit formula is of the form
,
where a₁ is the first term and r is the common ratio. Comparing this to our explicit form, we see that r = -4 and a₁ = 7.
The recursive formula is of the form
; using r=-4 gives us
Stove area = 12 square feet
Refrigerator area = 20 square feet
Entire kitchen floor = 270 square feet
12 + 20 = 32 square feet
270 square feet - 32 square feet = 238 square feet
238 square feet will be needed
