The sequence:
a 1 = 30, a 2 = 70, a 3 = 110, a 4 = 150, a 5 = 190,...
a 2 = a 1 + d
70 = 30 + d
d = 70 - 30 = 40
a n = a 1 + ( n - 1 ) * d
For the 25th month:
a 25 = 30 + 24 * 40 = 30 + 960 = 990
Answer: B ) 990.
<span>the 30°-60°-right triangle theorem states that the
</span>In a right triangle, the hypotenuse is twice as long as a leg if and only if the measure of the
<span>angle opposite that leg is 30°
so the option C is correct from above all

Answer:
C
Step-by-step explanation:
Given
+
← factor the denominator of first fraction
=
+ 
Multiply the numerator/ denominator of second fraction by (x + 2)
=
+ 
The denominators are now common, so add the numerators leaving the denominator, that is
= 
=
→ with numerator 4x + 6 → C
one tip:
Example: 4 - (-3)
it instantly becomes positive because the negatives are close to each other as shown.
hope that helps :)
