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 ) .

Ok so find 20% off and see if less tha 75
percent means parts out of 100
20% means 20/100=1/5

'of' means multiply

20% of 80=1/5 times 80=16

off means subtract
disctoun tof 16 is 80-16=64
64<75

how much left over
75-spent=left over
75-64=11

anwwer is $11 left over and enough money to buy

A Family has five children . The probability of having a girl is 1/2. What is the probability of having 2 girls followed by 3 bo

NeTakaya

Probability of having a girl: 1/2
Probability of having another girl right after: 1/2
Probability of having a boy right after: 1/2
Then another boy: 1/2
And a third boy: 1/2

To find compound probabilities, just multiply them together.

$\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2} = \frac{1}{2*2*2*2*2} =\frac{1}{32} = \boxed{0.031}\ in\ decimal\ form$
