Answer:

\left(x+2\right)\left(x+3\right)

Step-by-step explanation:

x^2+5x+6\\\\\mathrm{Break\:the\:expression\:into\:groups}\\=\left(x^2+2x\right)+\left(3x+6\right)\\\\\mathrm{Factor\:out\:}x\mathrm{\:from\:}x^2+2x\mathrm{:\quad }x\left(x+2\right)\\\\\mathrm{Factor\:out\:}3\mathrm{\:from\:}3x+6\mathrm{:\quad }3\left(x+2\right)\\=x\left(x+2\right)+3\left(x+2\right)\\\\\mathrm{Factor\:out\:common\:term\:}x+2\\=\left(x+2\right)\left(x+3\right)

Find tanX if cotX =2
Tom [10]

Answer:

1/2

Step-by-step explanation:

Let's define these trigonometric functions:

- tangent (tan): opposite / adjacent

- cotangent (cot): adjacent / opposite

Basically, tangent and cotangent are reciprocals of each other.

We know that cot(x) = 2. The reciprocal of 2 is 1/2, which means that tan(x) = 1/2.

Thus, the answer is 1/2.

2(4x -4) + 8x = 2 (8x -3) solve for x please
Brrunno [24]

Answer:

No Solutions

Step-by-step explanation:

Let's solve your equation step-by-step.

2(4x−4)+8x=2(8x−3)

Step 1: Simplify both sides of the equation.

2(4x−4)+8x=2(8x−3)

(2)(4x)+(2)(−4)+8x=(2)(8x)+(2)(−3)(Distribute)

8x+−8+8x=16x+−6

(8x+8x)+(−8)=16x−6(Combine Like Terms)

16x+−8=16x−6

16x−8=16x−6

Step 2: Subtract 16x from both sides.

16x−8−16x=16x−6−16x

−8=−6

Step 3: Add 8 to both sides.

−8+8=−6+8

0=2

Answer:

There are no solutions.
