Answer:

6cm ; 22cm

Step-by-step explanation:

Given that:

Total Length, AD = 28cm

AB =x cm

BC = (x +5)cm

CD = 2x - 1 cm

4x + 4 = 28

4x = 28 - 4

4x = 24

x = 24 / 4

x = 6cm

The length of BD

BD = BC + CD

BD = (x + 5) + (2x - 1)

x = 6

BD = (6 + 5) + (2(6) - 1)

BD = 11 + (12 - 1)

BD = 11 + 11

BD = 22 cm

N = 400(1.25^t); 3725

PLEASE HELP, BRAINLIEST FOR THE BEST ANSWER
Zolol [24]

Answer:

Use the distance formula to determine the distance between the two points.

Distance

=

√(x2−x1)^2 + (y2−y1)^2

Substitute the actual values of the points into the distance formula.

√ ( (−6) − 0)^2 +( (−3) − 4)^2

Subtract 0 from −6

√(−6)^2 + ( ( −3 ) −4 )^2

Raise −6 to the power of 2

√36 + ( ( −3 ) −4 )^2

Subtract 4 from −3

√36 + ( −7 )^2

Raise −7 to the power of 2

√ 36 + 49

Add 36 and 49

√85
