Answer:
See below
Step-by-step explanation:
To solve for d, multiply both sides of the equal sign by 4.
4(1/4d) = 4 (1/5g(g+e)-h)
4/4d = 4(1/5
+ 1/5ge - h)
d = 4/5
+ 4/5ge - 4h
Answer:
X^2 +x -6 or the last option
Step-by-step explanation:
If О is the center of a circle then:
<span>
OA = OB = OC = OD [radii]
AB = AH + HB = 15 + 15 = 30 </span>⇒ AB = CD
<span>
So </span>ΔAOB ≅ ΔCOD [SSS rule] ⇒ x = OH = 16 units.
Answer is a1 = 7
Using equation (derived from formula to find sum of values in a geometric series),

Hence, solve for a.
