Answer:
x = - a
Step-by-step explanation:
Multiply both sides by 2 to eliminate the fraction
2T = n(a + x)d
Since n and d are both multipliers, divide both sides by nd
= a + x
Isolate x by subtracting a from both sides, hence
x = - a

Plug in 0 to the equation as the t value to find the starting height the firework was launched, meaning the height of the platform.
Answer:
The answer is D. Variable. The "letters after the numbers" are always variables. A coefficient is the number that the variable is being multiplied by. An exponent would be something like this: with the 2 being the exponent. A binomial is an algebraic expression of the sum or the difference of two terms.
6 1/2 x 1 8/13
13/2 x 21/13 = 273/26 = 10 1/2
The answer is C, 10 1/2.
