2. d. all real numbers (i think)
3. d. all real numbers (i think)
Answer:
Third graph C.
Step-by-step explanation:
3a + 11 > 5
Subtract 11 from both sides
3a > -6
Solve for a
a = -6/3
a > -2
so a would be all numbers greater than -2
Answer:
(c) x² -64
Step-by-step explanation:
The factoring of the difference of squares is one of the special forms we use in the study of polynomials. It tells you ...
a² -b² = (a +b)(a -b)
__
You have a factor (x +8), so a=x, b=8, and the "expanded" form is ...
a² -b² = x² -8² = x² -64
Hope this helps, so sorry if I am wrong!
