u19=-71.74

Step-by-step explanation:

u5=a+4d=-3.7....(1)

u15=a+14d=-52.3....(2)

-10d=48.6

d=-48.6/-10

d=-4.86

Substitute-4.86 into....(1)

u5=a+4(-4.86)=-3.7

a+(-19.44)=-4.7

a=-3.7-(-19.44)

a=15.74

19term=a+18d=?

=15.74+18(-4.86)

=15.74+(-87.48)

19th term =-71.74

Find the value of BC B 4x - 10 C A D 3x + 5
Rainbow [258]

Answer:

BC = 50

Step-by-step explanation:

BC = AD in a parallelogram

4x-10 = 3x+5

Subtract 3x from each side

4x-3x-10 = 3x-3x+5

x-10 = 5

Add 10 to each side

x-10+10 = 5+10

x = 15

BC = 4x-10 = 4*15-10 = 60-10 = 50
