The product would expand to
This is a trinomial, and the only way to make it a binomial is to cancel out a coefficient using our variable .
So, we can cancel either the linear term or the constant term.
In the first case, we require
In the second case, we require
But must be a non-zero rational number, so this solution is not feasible.
Answer:
7 1/7.
Step-by-step explanation:
The middle 2 numbers in the expansion will be cancelled out if one of them is + 50 t so the required rational number is 50/7:
(7t - 10)(5t + 50/7) = 35t^2 - 50t + 350/7 t - 500/7)
= 35t^2 - 50t + 50t - 500/7)
= 35t^2 - 500/7)
So 50 / 7 = 7 1/7 (answer).
A
If you translate left one unit, then reflect across the x axis, you get the ending figure
5:10
$5-money he saves
$10-money he can spend
(18 x 4) * 5 = 360
(18 x 4) * 5 = 1320
15 x (4 x 20) = 1200
