<h3>
Answer: Choice A. x^2+9</h3>
This is a sum of squares, which cannot be factored over the real numbers. You'll need to involve complex numbers to be able to factor, though its likely your teacher hasn't covered that topic yet (though I could be mistaken and your teacher has mentioned it).
Choice B can be factored through the difference of squares rule. Therefore, choice B is not prime.
Choice C and D can be factored by pulling out the GCF and then use the difference of squares rule afterward. So we can rule out C and D as well.
<u>k / 9 = 12</u>
Multiply each side of the equation by 9 : <em>k = 108</em>
<u>84 n = 504</u>
Divide each side of the equation by 84 : <em>n = 6</em>
<u>6 = m / 148</u>
Multiply each side of the equation by 148 : <em>888 = m</em>
The sum of the angles in a triangle is always 180°.
49 + R + 80 = 180
180-129=51
Now,
We know that line PX = 180° because it’s a straight line
51 +
180+51 = 129
a) is correct
C= 2pir
= piD
D= C/pi
= 47/pi
= 14.96 (to 2 decimal places)
Answer:
32
Step-by-step explanation:
16,000 = (2^7)(5^3)
So, the number of positive divisors of 16,000 = (7+1)(3+1)
= (8)(4)
