Use the Difference of Squares rule to multiply (7x−3)(7x+3)<br> HELPPPP

Luda [366]

Answer:

x^4 + 7x^3 + 12x^2

Simplifying

x4 + 7x3 + 12x2

Reorder the terms:

12x2 + 7x3 + x4

Factor out the Greatest Common Factor (GCF), 'x2'.

x2(12 + 7x + x2)

Factor a trinomial.

x2((4 + x)(3 + x))

Final result:

x2(4 + x)(3 + x)

107/ 10 to the fourth power, simplified and kept in exponential form.

Alex Ar [27]

Answer:

1.07^(-2)

12 yellow balls and 9 red balls are placed in an urn. Two balls are then drawn in succession without replacement. What is the pr

denis23 [38]

Answer:

$\frac{9}{35}$

Step-by-step explanation:

When the first draw is done there are 9 red balls in a sample size of 21. So there probability of drawing a red ball will be $\frac{9}{21}$

When the second draw is done, there will be 12 yellow balls in a sample size of 20 since the first ball will not have been replaced into the bag. So the chance of someone drawing the second ball in the second draw is $\frac{12}{20}$

The probability of them happening in this order is the product of both probabilities:

$\frac{9}{21} * \frac{12}{20} = \frac{9}{35}$
