Answer:

$x = - 4 \\ x = - 7$

Step-by-step explanation:

$x {}^{2} + 28 = - 11x \\ x {}^{2} + 11x + 28 = 0 \\ x {}^{2} + 7x + 4x + 28 = 0 \\ x(x + 7) + 4(x + 7) = 0 \\ (x + 4)(x + 7) = 0 \\ \\ x = - 4 \: \: \: \: \: \: \\ \: x = - 7$

Ginger's baby weighed only 3 3/8 pounds when it was born. The doctor said it could not leave the hospital until it weighed 5 1/2

Elanso [62]

To subtract 3 3/8 from 5 1/2,
by turning into fractions
[(5x2)+1]/2 = 11/2
[(3x8)+3]/8 = 27/8
 11/2 - 27/8
To subtract fractions, your denominator needs to have the same number. so multiply it by 4
44/8 - 27/8 = (44-27)/8 = 17/8.
17 / 8 pounds or 2 and 1/8 because 17 / 8 = 2 remainder 1.
In terms of weight that is 2.125 pounds.

To prove part of the triangle midsegment theorem using the diagram, which statement must be shown?

miskamm [114]

The statement which the diagram shows is that the length of GH is half of the length of KL . Option B

<h3>What is the midsegment theorem?</h3>

The midsegment theorem holds that any segment that forms the joining midpoints of two sides of a triangle is parallel to half the length of the third side.

It can be seen that the length of GH is half of the length of KL as deduced from the diagram

Therefore, the statement which the diagram shows is that the length of GH is half of the length of KL . Option B
