Answer:

x = -2   or   x = -1/3   or   x = 1/3

Step-by-step explanation:

9x³ + 18x² - x - 2​ = 0

9x²(x+2) - (x+2) = 0

(x+2)(9x²-1)=0

(x+2)(3x+1)(3x-1)=0

x = -2   or   x = -1/3   or   x = 1/3

GarryVolchara [31]
1) suppose for purposes of calculation that the cake is inscribed in a square of 8 by 8
the area of 1 cake=8*8=64 in²
the rectangular table area=576 in²-----> I assume square table 24 in x 24 in
576/64= 9----------- > Sue has baked 9 cakes
if just 1 carrot cake
then
(9-1)=8 ---------->  coffee cakes and lemon cakes
we know that equal numbers of coffee cakes and lemon cakes
therefore
coffee cakes=8/2=4
lemon cakes=4
carrot cake=1

the answer part 1) is
the dimensions of the table are 24 in x 24 in

the answer part 2) is
Sue has baked 9 cakes
coffee cakes=4
lemon cakes=4
carrot cake=1

part 3) distribution of the cakes in the table 24  in x 24 in

answer

let
Z------->carrot cake
C------->coffee cakes
L------->lemon cakes

Z-C-L    or      C-L-C

Pls solve this I need explanation also for this pls pls
Westkost [7]

Answer: 220 yards

Step-by-step explanation:

1 mile equals 1,760 yards

1,760 ÷ 8 = 220 yards

8/8 is 1... so that 1 is equal to the 1,760

You could divide it by 8 as shown above OR to double check yourself.. take your answer of 220 yards and add that 220 to 220 a total of 8 times which will give you your 1 mile equaling to 1,760 total yards which makes 1/8 mile equal the 220 yards. (I really hope this helps and makes sense as to how I figured that out for you:-) )
