Answer:
a = 4.
Stepby-step explanation:
x^2 - 4 = (x + 2)(x - 2).
The answer to this question is B, because neither of suggestsions make sense
I don’t know what your trying to find but you basically create an equation, like this
3x+5x=80
and solve which would result in x=10
so there is
30 geckos
and
50 anole lizards
Answer:
105 degrees
Step-by-step explanation:
You first add 5 and 7 which gives you 12. Then, since two supplementary angles add up to 180, you divide 180 by 12 which gives you 15. Next, since 7 is the larger of the two, multiply 7 by 15 giving you 105. To check your work, subtract 105 from 180 giving you 75. Next, put this as a fraction- 75/105 and simplify giving you 5/7 which can also be written as 5:7.
2x+9<0
This is asking for numbers below 0
x>-12
This is asking for numbers above - 12
So the numbers which would fit in both of these rules would be:
-11, -10, -9, -8, -7, -6, -5
Any numbers above or below these wouldn't fit into any of the inequalities
