ΔABC ≅ ΔEDC by the SAS postulate.

<h3>What is the SAS postulate's conclusion?</h3>

Postulate of Side-Angle-Side (SAS) ,The two triangles are said to be congruent if two sides and the included angle of one triangle match those of another triangle by two sides and the included angle.

According to the SAS Postulate, two triangles are congruent if their two sides and included angles are identical to those of another triangle's two sides and included angle

The midpoint of DB and AE Given is at C.

BC ≅ CD Two equal portions are produced by the midway C.

AC ≅ CE Two equal portions are produced by the midway C.

ACB and DCE Congruent vertical angles exist.

By the SAS postulat, ABC becomes EDC.

A swimming pool can be filled in 15 hours if water enters through a pipe​ alone, or in 23 hours if water enters through a hose a
kykrilka [37]

Answer:

9.08 hours

Step-by-step explanation:

in order to fill 1 pool

fill rate by pipe = 1 pool / 15 hours = 1/15 pool per hour

fill rate by hose = 1 pool / 23 hours = 1/23 pool per hour

combined rate = fill rate by pipe + fill rate by pool

= 1/15 + 1/23 = 38/345 pool per hour

since:

38/345 pool ----------->  will take 1 hour

1 pool --------------------> will take 1 hour x (345/38) = 9.08 hours

Find the slope, distance and midpoint between
Dovator [93]

Answer:

Slope- 4

Distance- 12.4

Midpoint- (6,8)

Step-by-step explanation:

Slope- \frac{y2-y1}{x2-x1}

\frac{2-14}{4-7} =\frac{-12}{-3}=4

Distance- d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}

d = \sqrt{(4 - 7)^2 + (2-14)^2}

d = \sqrt{-3^2 + -12^2}d = \sqrt{144+9}=\sqrt{153}

\sqrt{153} = 12.4

Midpoint- \frac{x1+x2}{2} ,\frac{y1+y2}{2}

\frac{7+4}{2} =\frac{12}{2} = 6=x

\frac{14+2}{2} = \frac{16}{2} = 8 = y

(6,8)

Step-by-step explanation:

you have to find the discriminant

b²-4ac for each equation

if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots

if discriminant = 0 there is only one solution

if discriminant > 0 two real solutions

for your given problems

A. discriminant =(-2)²-4*2*15 will be negative
