Answer: -7, 12
Step-by-step explanation:
a+b = 5
a*b = -84
a = 5-b
(5-b)*b = -84
-b^2 + 5b + 84 = 0
(-b - 7)(b + 12) = 0
The roots are -7 and 12.

Answer:
Value of Y = 5√2 units
Step-by-step explanation:
Given:
Perpendicular = X
Base = Y
Hypotenuse = 10
Find:
Value of Y
Computation:
Cos θ = Base / Hypotenuse
Cos 45 = Y / 10
1/√2 = Y / 10
Value of Y = 5√2 units

Answer:
For first equation:
x = 18.5
For second equation:
x = 4.25
Step-by-step explanation:
First one:
-2x + 54 = 17. Subtract 54 on both sides.
-2x = -37. Divide all by -2.
x = 18.5
Second one:
4x - 54 = -9. Add 54 to both sides.
4x = 45. Divide all by 4.
X = 4.25.
