Answer:
2.5
Step-by-step explanation:
you can use pythag theorem and divide c by two:
-3^2+4^2=c^2
9+16= 25
c=5
however, 5/2=2.5
Answer:
E. x² + 11x - 42 = 0
Step-by-step explanation:
let the square sides be x
A = bh = (x + 3 + 3)(x + 2 + 3) = 72
(x + 6)(x + 5) = 72
x² + 11x + 30 = 72
x² + 11x - 42 = 0
Quarter: 7/27
nickel: 3/27=1/9
the 27 came from adding the amount of coins
7+8+3+9=27
