The sum of the first n terms in a geometric sequence given the first term (a1) and the common ratio (r) is calculated through the equation,
<span>Sn </span>= (<span><span><span>a1</span>(1−<span>r^n</span>) / (</span><span>1−r)
Substituting the known terms,
Sn = (20)(1 - (1/4)^4)) / (1 - 1/4)
Sn = 26.5625
Thus, the sum of the first four terms is 26.5625. </span></span>
First, you would have to do 11x + 3x Since you're combining like terms.
Now your problem is 14x + 40 = -24
Now you would do 40 - -24 which is now 40+24 and equal to 64.
Now you divide 14 by 64 and you get 4.5

Step-by-step explanation:
Answer:
Area of a triangle = A = 
Step-by-step explanation:
Given Data:
height of a triangle = h = 15 in
base of a triangle = b = 2 feet = 2*12 =24 in
To Find Out:
Area of a triangle = A = ?
Formula:
Area of a triangle = A = 
Solution:
Area of a triangle = A =
Area of a triangle = A = 
Area of a triangle = A = 
Area of a triangle = A =
Equation for what? Amount after so and so number of years?
If so, then A = $70(1+0.10)^t, where t is the # of years.
