Answer:

The value of BC is 30.

Step-by-step explanation:

Given information: A, B, and C are collinear, B lies between A and C, AC = 48, AB = 2x+2, and BC = 3x+6.

If A, B, and C are collinear, B lies between A and C, then by using segment addition property, we get

AB+BC=AC

Substitute AC = 48, AB = 2x+2, and BC = 3x+6 in the above equation.

(2x+2)+(3x+6)=48

On combining like terms we get

(2x+3x)+(2+6)=48

5x+8=48

Subtract 8 from both sides.

5x=48-8

5x=40

Divide 5 from both sides.

x=8

The value of x is 8.

We need to find the value of BC.

BC=3x+6\Rightarrow 3(8)+6=30

Therefore the value of BC is 30.

Answer:

BC=30

Step-by-step explanation:

AC = 48

AB = 2x+2

BC=3x+6

AC= AB + BC

48 = 2x+2+3x+6

48=5x+8

5x=40

x=8

Hence

BC = 3(8)+6

BC=24+6

BC=30

I think the answer is 21. I’m not sure but if I remember it’s 40 + 20 = 60. 180 - 60 = 120 and then it’s a vertical angle which is equal so then it would be 120 + 39 = 159. Then 180 - 159 = 21. Sorry if this is wrong I haven’t done this in a while. Have a good day!

Simplify the expression to a polynomial in standard form.<br> (x-2)(x2 +7x +4)
goldenfox [79]

Answer:

Step-by-step explanation:

(x  - 2)(x² + 7x + 4) = x(x² + 7x + 4) - 2*(x² + 7x + 4)

                              = x*x² + x*7x + 4*x  - 2*x² -2* 7x -2* 4

                               = x³ + 7x² + 4x - 2x²  -14x -8

                                = x³ + <u>7x² - 2x²</u>    <u>+  4x - 14x</u> - 8

                                = x³ + 5x² - 10x - 8
