Answer:

<h2>x + 1</h2>

Step-by-step explanation:

\dfrac{x^2+5x+4}{x+4}\\\\x^2+5x+4=x^2+x+4x+4=x(x+1)+4(x+1)=(x+1)(x+4)\\\\=\dfrac{(x+1)(x+4)}{x+4}\qquad\text{cancel}\ (x+4)\\\\=x+1

The endpoints of a line segment are A(-7, -2) and B(2, 4). The segment partition is (-3.4, 0.4). Find the ratio. HELP ASAP!!
Otrada [13]

Answer:

4.33 : 6.49

Step-by-step explanation:

Given endpoints as A(-7,-2) and (2,4) find the length of the segment

d=√ (x₂-x₁) + (y₂-y₁)²

d=√ (2--7)² + (4--2)²

d=√ 9² + 6²

d= √ 81 +36

d=√117 =10.82

The partition is at (-3.4,0.4)

The length from A to the partition will be

A(-7,-2)    (-3.4,0.4)

√ (-3.4--7)² + (0.4--2)²

√ 3.6²+2.4²

√18.72 = 4.33

Length of segment from partition to end point B

(-3.4,0.4)   ,  B(2,4)

√(2--3.4)²+(4-0.4)²

√ 5.4² + 3.6²

√42.12

=6.49

The ration that results from the partition of the segment is;

4.33 : 6.49
