Answer:
A. 169 is the correct answer
Answer:
18
Step-by-step explanation:
16 |‾‾‾288‾‾‾
16 goes into 28 once = 1 (as the tens digit = 10)
28-16=12 (remainder)
128/16 =8
10 + 8 = 18
If you factor the equation you can see what the solutions are. Two factor a quadratic of the form ax^2+bx+c, find two values which satisfy two conditions...
jk=ac=-15 and j+k=b=-2 so j and k must be -5 and 3 so the factors are:
(x-5)(x+3)
So the other solution is x=5
5x-y=0
3x+y=24
2x=-24
x=-12
-36+y=-24
y=-24+36
y=12

Put 65 over 100 so it's a fraction and simplify from there i think
