Solve each equation by factoring x^2+4x+4=0 ​

Mathematics
1 answer:
makkiz [27]4 years ago
6 0

Answer: x = -2

<u>Step-by-step explanation:</u>

Find 2 numbers whose product is the c-value of 4 and their sum is the b-value of 4.

x² + 4x + 4 = 0

              ∧

           1 + 4 = 5  

           2 + 2 = 4  <em>this works!</em>   <em>so the factors are: </em>

(x + 2)(x + 2) = 0

x + 2 = 0      and      x + 2 = 0

     x = -2      and             x = -2  --> <em>same answer so only need to list it once</em>

157=2(3.14)r

Solve for r

r=157/6.28=25\ ft

Which are lines that will intersect? which are perpendicular lines? which are skew lines?
Anarel [89]

By using the concept of line, coplanar, non parallel lines always intersect

Definition of perpendicular and skew lines has been given

What is a line?

A geometrical object which has only length but no breadth and height is  called a line

The lines which are coplanar and are not parallel will intersect at some point

Two lines are said to be perpendicular to each other if the angle between them is 90°

The lines which are not parallel, non coplanar at do not intersect are called skew lines.

△ABC is an isosceles triangle with legs AB and AC. △AYX is also an isosceles triangle with legs AY and AX. The proof that △ABC ~
Maslowich

Answer with explanation:

Given:  △ABC is an isosceles triangle with legs AB and AC.Also, △A Y X is also an isosceles triangle with legs A Y and AX.

To Prove: △ABC ~ △A Y X

Proof with Statement

1. △ABC is isosceles with legs AB and AC; △A Y X is also isosceles with legs A Y and AX.

2.AB ≅ AC and A Y ≅ AX.→definition of isosceles triangle

3.AB = AC and A Y = AX →→ definition of Congruency.

4.→→A Y × AC=AX × AC⇒[Multiplication property of equality]

5.≡A Y × AC=AX × AB⇒[Substitution property of equality]

6.\rightarrow\frac{AB}{AY}=\frac{AC}{AX}

----------------[Division property of equality]

7.Also, ∠A is common angle between two triangles.That is,

 ∠A=∠A------------[Reflexive property]

⇒Missing statement and Reason in the entire proof.

8.△ABC ~ △AYX----[SAS]
