Answer:
(8x-7)(8x+7)
Step-by-step explanation:
This is a difference of squares polynomial of the form
. Since 64 and 9 are both perfect squares then take the square root of each so a=8 and b=7.
Factors:(8x-7)(8x+7)
The answer is D. First add 2k, then divide by a, the subtract x, then divide by -1
From 10 to 23, all you do is write in radical form.
For example, number 10, the answer would be
![\sqrt[5]{y}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7By%7D%20)
The denominator, 5, goes on top of that radical sign and the 1 is the exponent of y. That's what you have to do for 10 to 23.
Now 24 to 39 is just the opposite. You change it to exponent form.
For example, number 24, the answer would be
For 40 to 47, you have to neutralize the negatives or get rid of it, so you have to use the rule of negative exponents.
For example, number 40, the answer would be
![\frac{1}{x^{ \frac{1}{3} } }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bx%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%7D%20)
For 48 to 55, you use multiply it but when multiplying exponents, you have to add.
For example, number 48, the answer would be
![5^{ \frac{6+1}{8} } = 5^{ \frac{7}{8} }](https://tex.z-dn.net/?f=5%5E%7B%20%5Cfrac%7B6%2B1%7D%7B8%7D%20%7D%20%3D%205%5E%7B%20%5Cfrac%7B7%7D%7B8%7D%20%7D%20%20)
You don't need to multiply the two 5s because they are the bases.
Hope this helps.
Answer:
6 feet . 3.9843 Inches 1 M =3.28 foot
Answer:
y ≥ -5
Explanation:
y is greater than -5 because the darkened line is heading towards the positive side.
(The positives are greater than the negatives.)
(The smaller negative numbers are greater than the larger negative numbers.)
