The denominator( s ) we are given are x^2 + 4x + 4, and . The first thing we want to do is factor the expressions, to make this easier -

x^2 + 4x + 4

This expression is a perfect square, as ( x )^2 = x^2, ( 2 )^2 = 4, 2 * ( x ) * ( 2 ) = 4x. Thus, the simplified expression should be the following -

( x + 2 )^2

The other expression is, on the other hand, not a perfect square so we must break this expression into groups and attempt factorization -

x^2 + 5x + 6,\\\left(x^2+2x\right)+\left(3x+6\right),\\x\left(x+2\right)+3\left(x+2\right),\\\left(x+2\right)\left(x+3\right)\\\\Factored Expression = \left(x+2\right)\left(x+3\right)

Combining ( x + 2 )^2 and ( x + 2 )( x + 3 ), the expression that contains factors of each is ( x + 2 )^2 * ( x + 3 ), or in other words the LCM.

<u><em>Solution = </em></u>\left(x+2\right)^2\left(x+3\right)<u><em /></u>

Step-by-step explanation:

43. P, U

44. 7

53. Airplanes can be traveling on different planes, one plane above the other. Cars on the same intersection are on the same plane.

55

a. You can choose (4 * 3 * 2)/(3 * 2) = 4 groups of 3 points in which order does not matter.

One of those combinations does not have K, so 3 combinations of the 4 have K.

p = 3/4

b. p = 1 since any three points are always coplanar.

(2y+9)+(3d+5)=? *simplify your answer*
netineya [11]

Answer:

2y + 3d +14\\2(y+7)+3d

Step-by-step explanation:

We remove the bracket and rearrange the numbers to add them. Only similar variables can be added together.

(2y+9)+(3d+5)\\2y+9+3d+5\\2y + 3d + 9 +5\\2y + 3d + 14\\2(y+7)+3d
