8/10
4x2=8
5x2=10
this is how you know they are equal
What is supposed to be the underlined digit
Answer and Step-by-step explanation:

<u>Step 1: Simplify both sides of the equation:</u>




<u>Step 2: Subtract 5/6 from both sides:</u>


<u>Step 3: Multiply both sides by 15/2:</u>


Answer:

Step-by-step explanation:
<u>Trigonometric ratios</u>

where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Given:
= G- A = GF = 2
- H = EG = 4

Steps to solve for the zero:
(x + 7)(x + 5) = 0
~Set both factors to equal zero
x + 7 = 0
x + 5 = 0
~Solve for x in [ x + 7 = 0 ]
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
~Solve for x in [ x + 5 = 0 ]
x + 5 = 0
x + 5 - 5 = 0 - 5
x = -5
Therefore, the solutions are x = -7 and x = -5
Best of Luck!
