Answer:
the two number are 7 and 9
Step-by-step explanation:
2*x+y=25
3x-y = 20
add the two equations
2*x+y=25
3x-y = 20
---------------
5x = 45
divide by 5
5x/5 = 45/5
x = 9
lets find y
2x+y = 25
substitute x
2*9 +y =25
18+y =25
subtract 18 from both side
y = 25-18
y =7
Answer:
Step-by-step explanation:
surface area=4 *x²+2 x²=6x²=6 ×5²=150 sq. in.
We can form this algebraic equation to work the equation out:
16 + 2x = -24
2x = -40
x - 20
