Answer:

Explained

Step-by-step explanation:

In trapezoid only one pair of side is parallel to each other whereas in A parallelogram both pair of sides are parallel to each other. Although both are quadrilaterals with four sides. But according to above stated condition A a trapezoid can not be called a parallelogram.

hope you got the point and ask your doubts in comments

Answer:

874, 2445, 95, 27

Step-by-step explanation:

0 = 0

1 = 1

2 = 2

3 = 3

4 = 4

5 = 5

6 = 6

7 = 7

8 = 8

9 = 9

A = 10

B = 11

C = 12

D = 13

E = 14

F = 15

36A = 3 * 16^2 + 6 * 16^1 + 10 * 16^0 = 874

98D = 9 * 16^2 + 8 * 16 + 13 = 2445

5F = 5 * 16 + 15 = 95

1B = 1 * 16 + 11 = 27

If A = -3n + 2 and B = 5n - 7, what is the value of A - B, in simplest form?

11Alexandr11 [23.1K]

Answer:

-8n + 9

General Formulas and Concepts:

Pre-Algebra

Distributive Property

Algebra I

Combining Like Terms

Step-by-step explanation:

Step 1: Define

A = -3n + 2

B = 5n - 7

A - B

Step 2: Simplify

Substitute: -3n + 2 - (5n - 7)
Distribute negative: -3n + 2 - 5n + 7
Combine like terms (n): -8n + 2 + 7
Combine like terms (Z): -8n + 9

Parallelogram ABCD is given. Draw line EF so that it goes through the vertex A. Point E lies on the side BC and point F lies on

tresset_1 [31]

Answer:

The proof is explained step-wise below :

Step-by-step explanation :

For better understanding of the solution see the attached figure :

Given : ABCD is a Parallelogram ⇒ AB ║ DC and AD ║ BC

Now, F lies on the extension of DC. So, AB ║ DF

To Prove : ΔABE is similar to ΔFCE

Proof :

Now, in ΔABE and ΔFCE

∠ABE = ∠FCE ( alternate angles are equal )

∠AEB = ∠FEC ( Vertically opposite angles )

So, by using AA postulate of similarity of triangles

ΔABE is similar to ΔFCE

Hence Proved.

Using the point-slope formula, what is the equation of the line that passes through the points (1,5) and (0, 0)?

DerKrebs [107]

Answer:

y =5x

Step-by-step explanation:

$y_{1}-y_{2} = m(x_{1} - x_{2} )$

(5 - 0) = m(1 - 0)

5 = m(1)

5 = m

$y_{1}-y_{2} = m(x_{1} - x_{2} )$

y - 5 = 5(x - 1)

y - 5 = 5x - 5

y = 5x -5 + 5

y = 5x
