Answer:
Step-by-step explanation:
x + y = 7 ------------(I)
y = 7 - x ------------(II)
x + 2y = 11 --------------(III)
Substitute y = 7 - x in equation (III)
x + 2 * (7 -x) = 11
x + 2*7 - 2*x = 11
x + 14 - 2x = 11
x - 2x + 14 = 11
- x + 14 = 11
Subtract 14 from both side
-x = 11 - 14
-x = -3
Multiply both sides by (-1)
x = 3
Substitute x=3 in equation (II)
y = 7 - 3
y = 4
Answer:
yes!
Step-by-step explanation:
when we simplify this we will get 6b+3, which is a binomial so yes it is a polynomial!

3√5 / 4√5 The √5's cancel out
The answer is 3/4
This is because √5 is in both the denominator and the numerator, and so you can pull them both out.
