He makes 24 burgers because 6 times 4 is 24.
D - 21 ≥ 53
solve just like normally would using algebra.
add 21 to both sides
d ≥ 74
Answer: 165
Step-by-step explanation: To evaluate this expression, we simply plug the value of the variable into the expression and solve.
So here, since <em>n</em> is equal to 15, we have 150 + (15) which simplifies to 165.
The 8th term of the geometric sequence is 13122x^22
<h3>Explicit form of a geometric sequence</h3>
The explicit form of a geometric sequence is expressed according to the equation;
Tn = ar^n-1
where
r is the common ratio
a is the first term
n is the number of terms
Given the sequence below;
6x,18x^4,54x^7
r = 18x^4/6x
r = 3x^3
a = 6x
n = 8
Substitute to have:
T8 = 6x(3x^3)^8-1
T8 = 6x (3x^3)^7
T8 = 13122x^22
Hence the 8th term of the geometric sequence is 13122x^22
