In this question, we have to find all the products which result in a difference of perfect squares .
The formula of the difference between squares is
In the first option, we have
Which is of the form of difference of two squares. And similarly , the last option is also in the form of difference of two squares .
And for perfect squares, we have same factor twice in b and e, so for that b and e are the correct options .
So out of the given options, correct options are a,b,e and f .
Answer:
ONE: A
TWO:B
FIVE: E
SIX: F
Answer:
5000
Step-by-step explanation:
Round 9245 to the nearest thousand
9000
Round 4033 to the nearest thousand
4000
9000-4000 = 5000
Answer:
Sum 9,200 + 4,000 = 13,200
Difference 9,200 - 4,000 = 5,200

[MA]:
3: 80 weeks.
4: 5 hours
5: 26.25 teaspoons
The explanation:
3.
1st week = 20 walls
2nd week = 20 + 20 = 40 walls
3rd week = 20 + 20 + 20 = 60 walls
4th week = 20 + 20 + 20 + 20 = 80
Therefore, in 4 weeks. 80 walls in total will be painted.
4.
6 km in 3 hours
10 km in x hours
Proportion:
6 - 3
10 - x
Cross multiplication:
6x = 3 * 10
6x = 30 \ divide by 6
x = 5
It will take 5 hours.
5.
Tablespoon of vinegar taken (v) = 7
Tablespoon of baking soda taken (b) = 4
Therefore, ratio between v and b: 7 : 4
Tablespoon of vinegar taken (v) = x
Tablespoon of baking soda taken (b) = 15
Therefore, ratio between v and b = x : 15
7 : 4 : : x : 15
Produce of extremes = Product of means
26.25 teaspoons
