Answer:

Factors (12 - 7x) ( 12 +7x ) .

Step-by-step explanation:

Given  : 144 − 49x².

To find : Which is a factor .

Solution : We have given 144 − 49x²

We can write 144 = (12)².

                       49 = (7)².

Then  (12)² - (7x)².

By the formula (a)² - (b)² = (a-b) ( a+b) .

Here, a = 12 ,  b = 7x

 (12)² - (7x)² = (12 - 7x) ( 12 +7x ) .

Therefore, Factors (12 - 7x) ( 12 +7x ) .

hjlf

Answer:

4 11/16 m²

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

From the question:

Length = 1 1/4 m

Width = 3 3/4m

Area of the rectangle =

1 1/4 m × 3 3/4 m

= 5/4 m × 15/4 m

= 75/16 m²

= 4 11/16 m²

Area of the rectangle = 4 11/16 m²

7,16,8,27,9 what number continues this pattern
Aloiza [94]
The sequence seems to be that you add 1 and then multiply by 2, and then add 1 and multiply by 3, so I would assume you do 9 + 1 = 10, and then multiply by 4 to get 40 as your next number. I hope this helps!
