Answer:
5.3
Step-by-step explanation:
Use Pyth Theorem
a^2 + b^2 = c^2
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 28
Sq root of 28 = 5.3
Answer:
4x+y add like terms ... -5+9=4 and -y(or -1)+2y=y
Since both the expressions in x are equal to y then they are equal to each other, so
-2x + 3 = 13x - 4
-15x + 3 = -4
-15x = -7
x = 7/15
and y = -2(7/15) + 3 = 31/15 = 2 1/15
Answer: Negative
Step-by-step explanation: Since the values of A and B are both negative (because they are below 0), adding them together will also make the sum negative.
