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 ) .

Which is the completely factored form of 3x^2-12x-15
Luba_88 [7]

Find the GCF (Greatest Common Factor)

GCF = 3

Factor out the GCF ( Write the GCF first. Then, in parentheses, divide each term by the GCF)

3(3x^2/3 + -12x/3 - 15/3)

Simplify each term in parentheses

3(x^2 - 4x - 5)

Factor x^2 - 4x - 5

<u>3(x - 5)(x + 1)</u>

Answer:

Step-by-step explanation:

The rectangle has 4 corners of 90 degrees.

Here a rectangle is divided into two right triangles. In right-angled triangles, the opposite side at a 30-degree angle is half a chord...I replace x instead of length.. So x / 2 = 4--->x:8

The perimeter of a rectangle is equal to (length + width) × 2--->(8+4)×2=24m^2
