1)
45x^3+5x
the GCF is 5x because that is a factor of both.
The answer would be 5x(9x^2+1)

2)
u^2-5u+6
factoring is finding what multiplies to the last number to add to the middle number. Those numbers are -3 and -2.
the answer would be (u-3)(u+2)

3)
m^2-49
difference of perfect squares
answer is (m+7)(m-7)

4)
x^5+4x^4+3x^3
GCF is x^3 so it's x^3(x^2+4x+3)
Factor that and it's x^3(x+3)(x+1)

Which of the following is a solution of x2 + 2x + 8?

zubka84 [21]

Using the quadratic equation we get:
$\frac{ - 2 + - \sqrt{4 - 32} }{2} = \frac{ - 2 + - \sqrt{ - 28} }{2}$

Factoring out 2 we get
$\frac{ - 2 + - 2\sqrt{ - 7} }{2} = - 1( + - ) \sqrt{ - 7}$
Factoring out the imaginary number:
$- 1 + \sqrt{7} i \: (and) \: - 1 - \sqrt{7} i$
So b.

HELP ME PLEASE !!!!

For this one, an easy way to solve it is to break it down into parts. First lets convert 5 feet to inches.

Multiply the number of feet by how many inches are in one foot.

5 times 12= 60 in

Now just add the like terms

60 in + 2 in= 62 inches.

Now we see that Sarah is 62 inches tall, now we can convert to centimeters the same way.

62 times 2.54= 157.48

So that makes C your answer, Sarah is 157.48 cm tall.
