Answer:
for the first one, x + 3 * y = 5
and the second equation, x - y = 5
Step-by-step explanation:
the sum of two numbers means for example the sum of 5 and 8 is 13, so as an equation that is 5 + 8 = 13
the difference is the same thing as the sum but it's subtraction.
and then times is just multiplication.

P=6x+8
A=2x^2+11x-21
Perimeter:
P=2(x+7)+2(2x-3)
Area:
A=(x+7)(2x-3)
3a^2+12a-7
P(will make next shot) = 13/24. This is an experimental probability, based upon observation, not theory.
