Answer: what’s the answer ?
Step-by-step explanation:
B is related to the last term of trinomial
Last term on the left hand side of the equation = Last term on the right hand side of the equation.
The last term on the right hand side is gotten by multiplying all the terms on the right of the two expression.
-32y²= 2*-8y*By
-32y² = -16By² Compare both
32 = 16B
16B = 32
B = 32/16
B = 2.
2.5x + 2y = 336
x = 2y
2 equations, 2 unknowns, solvable
3.5x = 336
7x = 672
x = 672 / 7
x = 96
96 / 2 = y
y = 48
they sold 96 popcorn bags and 48 pretzels
