Answer:
i think it would just be B+A
Step-by-step explanation:
Answer:
* = b²
Step-by-step explanation:
You know that the square of a binomial is of the form ...
(x + y)² = x² + 2xy + y²
Matching given terms, we have ...
49 = y²
2xy = 14b
Solving the first of these relations for y, we have
y = √49 = 7
Putting that in the second relation and solving for x, we find ...
2x·7 = 14b
14x = 14b
x = b
Then the first term of the expansion, x², will be b².
The missing term is b².
Answer:
add up all the sides!!
6+3+3+3+5+12+4+6=38
so the perimeter is 38 ft
(20+2.5)x = cost
when x equals number of tickets
(20+2.5)24 = 540
