The product of a constant factor of four and a factor with the sum of two terms
Answer:
2x²+3x-54
Step-by-step explanation:
(2x-9)(x+6)
=x(2x-9)+6(2x-9)
=2x²-9x+12x-54
=2x²+3x-54
The value of p and q is 2 , -8 , The nth term of the series is given by 3 * n² + n-2 , the 40th term is 4838 .
<h3>What is a quadratic Sequence ?</h3>
A sequence which has n term in its sequence , The difference of the consecutive number is not same , its second difference is same.
The sequence is given as 7; p; -3;q;...
for a linear pattern
7-p = p- (-3) = -3-q
2p = 4
p = 2
and
2+3 = -3 -q
5 +3 = -q
q = -8
The value of p and q is 2 , -8
A quadratic sequence is defined as 2; 12; 28; 50
The next two terms are 77 and 112.
3. The T40 of the sequence is
The nth term of the series is given by
3 * n² + n-2
therefore 40th term is
3 *40² + 40-2
3 *1600 +38
4838
Therefore the 40th term is 4838 .

Answer:
Step-by-step explanation:
Right answer is choice C
Let a= amount Vince needs
Because if the least expensive phone is $225.90 and Vince got $122.35 saved then
(225.90 - 122.35) $103.55 is how much Vince will need
103.55 is greater than or equal to a
and not less than or equal to
