Answer: a, c
step-by-step explanation:
if a < 7 or a is less than 7
a.) a < 17 a is less than 17 so that’s true
b.) -a < -7 i’m not sure on this one but i believe no
c.) 3a + 4 < 25
-4 -4
3a < 21
/3 /3
a < 7 which is true
d.) a^2 < 49 i’m also not sure how to cancel out exponents but i hope the two definite answers help

16 is the answer. I can explain if you need
Answer:
197 million square miles
Step-by-step explanation:
Remark
What the equator is telling you is that the circumference around the earth is approximately 24902 miles. So before you can find the surface area, you need to find the radius of that circumference.
Equations
C = 2*pi*r
Area = 4pi*r^2
Solution
<em><u>Radius</u></em>
C = 24902
pi = 3.14
r = ?
24902 = 2 * pi * r
r = 24902 / (2 * pi)
r = 3965.29
==========
<em><u>Surface Area</u></em>
Area = 4 * pi * r^2
Area = 4 * 3.14 * 3965.29^2
Area = 4 * 3.14 * 15,723,498
Area = 197 000 000 square miles
Answer:
Step-by-step explanation:
Common difference = second term - first term
= 2 -(-5)
= 2 +5 = 7
16 + 7 = 23
23 + 7 = 30
30 + 7 = 37
Next three terms are: 23 , 30 , 37 , .......
