Answer:
5208
Step-by-step explanation:
How to solve?: First you will get you alike terms on the same side. You will do this by subtracting 5 on both sides of your sign and will therefore get the equation to where -5 and -3 is on the same side and looks like -5 - 3. Then you will combine your -5 and -3 and get -8. Now you will take your -2x and divide both sides by -2 to where your able to get your variable x alone. You will then get -8 divided by -2 and your answer would be -4.
Answer: -4

the last one is the answer (x+6)(x+6)
Answer:
Altitude of the jet is 10.40km
Step-by-step explanation:
The angle of elevation = 8°
Horizontal distance (adjacent to the angle) = 74km
Altitude of the plane (opposite) = ?
Kindly check attached document for better illustration.
To solve this question, we have to use tangent rule since we have adjacent and angle, but no opposite.
Tanθ = opposite / adjacent
θ = 8°
Adjacent = 74km
Opposite = ?
Tan 8 = x / 74
Opposite = 74 * tan8
Opposite = 10.40
The altitude of the jet is 10.40km
