Rectangle ABCD has vertices A(15, 18), B(−5, 3), C(1, −5), and D(21, 10).

erastova [34]

Answer:

1. 25

2. 10

3. 250

Step-by-step explanation:

Distance formula :√ (x2 - x1)² + (y2 - y1)² √ ()² + ()²

1. LENGTH OF AB :

A = 15,18

B = -5,3

√ (-5 - 15)² + (3 - 18)²

= √ 400 + 225

= 25

2. LENGTH OF AD :

A = 15,18

D = 21,10

√ (21 - 15)² + (10 - 18)²

= √36 + 64

= 10

AREA :

A=w x l

10 x25 = 250

Answer:

(x - 7)(x + 3)

Explanation:

$\rightarrow \sf x^2 - 4x - 21$

breakdown

$\rightarrow \sf x^2 - 7x +3x- 21$

factor out common terms

$\rightarrow \sf x(x - 7) +3(x- 7)$

collect into groups

$\rightarrow \sf (x+3)(x- 7)$
