Pqr is a straight line.
the length of pq is 6 times the length of qr.
pr=98cm
work out the length of pq
you must show all working.

PQR=PQ+QR

QR=1 unit

PQ=6 units

PQR=7 units

=98cm

7 units>98cm

1 unit>98÷7

=14cm

6 units>14×6

=84cm

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
