X + 3 5/8 = 7 1/4
x + 29/8 = 29/4
x = 29/4 - 29/8
x = 58/8 - 29/8
x = 29/8
x = 3 5/8

Answer:
area = 132 cm²
Step-by-step explanation:
area of rectangle = 7 x 12 = 84
area of one triangle = 8 x 6 x 0.5 = 24
total area = 84 + 24 + 24 = 132 cm²
Answer:
25x^2 - 60xy + 36y^2
Step-by-step explanation:
(5x - 6y) ( 5x - 6y)
Use foil to get the result when this is expanded.
F: (first term in each factor): 5x*5x = 25x^2
I: Use the last term first factor multiplied by first term second factor
- 6y * 5x = - 30xy
O:Outside. Use first term first factor and last term second factor
5x * -6y = - 30xy
L: last term in both factors -6y * - 6y = 36y^2
All them together
25x^2 - 30xy - 30xy + 36y^2
and combine
25x^2 - 60xy + 36y^2
41, 50, 59
all you have to do is subtract the first number from the second number which is 9. then you add 9 to the last number to get your answer
