Answer:
x = 33
y = 41
Step-by-step explanation:
GIven
x: number of nickels
y: number of quarters
A nickel = $0.05
A quarter = $0.25
then we have the system of equations
0.05*x + 0.25*y = 11.90
x + y = 74
Which can be solved applying any of known methods. Then, the solution is
x = 33
y = 41

Answer choice A so angle A is equivalent to angle D
To find the diagonal you do
side x the square root of 2
so your answer would be
8 1/2
Hope this helps ;)
Y^2+5y the greatest common factor is y so
y(y+5)
...
4x^2-49 this is a "difference of perfect squares" which always factors to:
(a^2-b^2)=(a-b)(a+b), in this case:
(2x-7)(2x+7)
...
5s^2-20 GCF is 5
5(s^2-4) now the parenthetic term is a difference of squares so
5(s-2)(s+2)
