Answer:
12; 8
Step-by-step explanation:
length-x
breadth-2/3x
2(x+2/3 x)=40
2×5/3x=40
10/3x=40
x=40÷10/3
x=40×3/10
x=12 (cm) length
2/3×12=8 (cm) breadth
Answer:
Step-by-step explanation:
We can write this as the difference of squares:
(5b⁸+8c)(5b⁸-8c)
To write as the difference of squares, take the square root of each term first:
√25b¹⁶ = 5b⁸; √64c² = 8c
Now we write this as a sum in one binomial and a difference in the other:
(5b⁸+8c)(5b⁸-8c)
Answer: On average, each country receives 2.93 inches of rain each day.
Step-by-step explanation:
Since we have given that
Palm Beach = 2.3
Broward = 3.5
Dade = 3.0
So,the average inches of rain each country would receive each day would be :

Hence, on average, each country receives 2.93 inches of rain each day.
Rewriting 278-159=119, we get 159 + 119 = 278. The first term is 159. If we add 119 once, we get 278; if we add 119 again, we get 397; and so on. This is an arithmetic sequence.
