Answer:
x^2+8x+8
Step-by-step explanation:
Distribute x^2 to x+2, which is x^2+4x.
Then, distribute 4 to (x+2), which is 4x+8
Add the like terms
x^2+4x+4x+8
x^2+8x+8
The elevation of the plane is 3600 ft
Let
- h = elevation of plane,
- d = distance from Marsha's house to spot on ground below plane = 3600 feet and
- Ф = angle of elevation of plane = 45°
From the triangle, we have the trigonometric ratio
tanФ = h/D
<h3>Elevation of the plane</h3>
Making h subject of the formula, we have
h = DtanФ
substituting the values of the variables into the equation, we have
h = DtanФ
h = 3600 ft × tan45°
h = 3600 ft × 1
h = 3600 ft
So, the elevation of the plane is 3600 ft

Answer:
simplify = - 4 x -2 factored = 2 (-2x - 1)
Step-by-step explanation:
Answer: 78
Step-by-step explanation:
X-intercept is when y=0;
4x-3(0)=12.3
4x=12.3
x=12.3/4
x=3.075 (x-intercept)
y-intercept is when x=0
4(0)-3y=12.3
-3y=12.3
y=12.3/-3
y=-4.1 (y-intercept)
Hope I helped :)
