Answer:

11. 4x^{3}-10x^{2}+6x

Take out 2x ( greatest common factor )
2x(2x^{2}-5x+3)

Factor

2x(2x^{2} -2x-3x+3)

2x(x-1)-3(x-1)=(2x-3)(x-1)

Don't forget about the 2x we took out earlier

Solution to 11: 2x(2x-3)(x-1)

12. 16x^{2} -25y^{2}

This is the difference of squares, so let's use the formula...

a^{2}-b^{2}=(a-b)(a+b)

if, a=16x^{2} and b=25y^{2}

then, the Solution to 12 is:

(4x-5y)(4x+5y)

13. 3x^3-24

First of all, you must find the greatest common factor because there isn't anything else you can do.

3(x^3-8)

Now you can see the difference of cubes...

a^3-b^3=(a-b)(a^2+ab+b^2)

so, the Solution to 13 is:

3(x^3-8)= 3(x-2)(x^2+2x+4)

Building A is 400 feet tall and Building B is 300 feet tall. Johnny is standing in between the two building. The angle of elevat
Free_Kalibri [48]

Answer:

389 feets apart

Step-by-step explanation:

Given that:

Building A

Height = 400feets

Angle of elevation = 70°

Building B:

Height = 300 feets

Angle of elevation = 52°

Distance from the foot of building A to where Jonny is standing = x (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 70 = 400/ x

2.7474774x = 400

x = 145.58809 feets

Distance from the foot of building B to where Jonny is standing = y (see attached picture)

Using trigonometry :

Tanθ = opposite / Adjacent

Tan 52 = 300/ y

1.2799416y = 300

y = 145.59

y = 234.38568 feets

x + y = distance between the two buildings

(145.58809 + 234.38568) feets

= 379.97377

= 380 feets apart
