Answer:
(4,1)
Step-by-step explanation:
x+y=5
x- y=3
Add the equations together to eliminate y
x+y=5
x- y=3
--------------------
2x = 8
Divide each side by 2
2x/2 = 8/2
x = 4
Now we can find y
x+y = 5
4+y = 5
Subtract 4 from each side
4+y-4 = 5-4
y =1
Answer:
probability sample
Step-by-step explanation:
5625 m^2
If is is square, all sides must be congruent (all sides are 75m). To find area, you multiply width x length (how long). Therefore:
75m x 75m = 5626 m^2
Answer:
6 + 3
+ 2
+ 
Step-by-step explanation:
Using the rule of radicals
×
⇔ 
Given
(3 +
)(2 +
)
Each term in the second factor is multiplied by each term in the first factor, that is
3(2 +
) +
(2 +
) ← distribute both parenthesis
= 6 + 3
+ 2
