Answer:

3x-3

Step-by-step explanation:

You have to combine like terms. <em>x</em> and 2<em>x</em> have the same variable, so this equals 3x, and then you subtract 3 so:

x-3=2x-3-x

=3x-3

Part A: Determine if the expression is one of our special products. If so, identify it by its general form:

kondaur [170]

Answer:

Part A: Yes, it is (a - b)².

Part B: a² - 2ab + b² => (x - 6)² = x² - 12x + 36.

Part C: x² - 12x + 36.

Part A: Not a special product.

Part B: Binomial distribution => (x + 8)(x + 1) = x² + 9x + 8.

Part C: x² + 9x + 8.

Part A: Yes, it is (a + b)²

Part B: a² + 2ab + b² => (3x + 2)² = 9x² + 12x + 4.

Part C: 9x² + 12x + 4.

Part A: Yes, it is (a + b)(a - b), a difference of squares.

Part B: a² - b² => 4x² - 49

Part C: 4x² - 49

Part A: Not a special product.

Part B: Binomial distribution => (x - 5)(2x - 5) = 2x² - 15x + 25.

Part C: 2x² - 15x + 25

Point A is the midpoint of side XZ and point B is the midpoint of side YZ. Triangle X Y Z is cut by line segment A B. Point A is

AveGali [126]

Answer:

<h3>B. 4units</h3>

Step-by-step explanation:

Find the diagram attached. The diagram is a similar triangle.

From the diagram, XZ/XY = CA/AB

Given XZ = 2x-2+2x-2 = 4x-4

XY =5x-7

CA = 2x-2

AB= x+1

On substituting this parameters into the formula to get x first

4x-4/5x-7 = 2x-2/x+1

cross multiply

(4x-4)(x+1) = 5x-7(2x-2)

open the parenthesis

4x²+4x-4x-4 = 10x²-10x-14x+14

4x²-4 = 10x²-24x+14

10x²-4x²-24x+14+4 = 0

6x²-24x+18 = 0

x²-4x+3 = 0

x²-3x-x+3 = 0

x(x-3)-1(x-3) =0

(x-3)(x-1) = 0

x = 3 and 1

Next is to get length AX.

Given AX = 2x-2

Substitute x = 3 into the expression

AX = 2(3)-2

AX = 6-2

AX = 4 units

Hence the measure of length AX is 4 units

Solve this proportion: 1/c+5=2/3

Fittoniya [83]

$\frac{1}{c} +5=\frac{2}{3}\ \|\ subtract\ 5\ to\ both\ sides \\\\\frac{1}{c} =\frac{2}{3}-5\\\\\frac{1}{c} =\frac{2}{3}-\frac{15}{3}\\\\\frac{1}{c} = \frac{-13}{3}\\\\-13c=3\ \ | \ divide \ both \ sides\ by\ (-13)\\\\c=-\frac{3}{13}$

$\frac{1}{c+5} = \frac{2}{3} \\\\2(c+5) =3\\\\2c+10=3\ \ |\ subtract\ 10\ to\ both\ sides \\\\ 2c=3-10 \\\\2c=-7 \ \ | \ divide \ both \ sides\ by\ 2 \\\\c=-\frac{7}{2}\\\\c=-3.5$
