6a perimeter is 12 cms and 28cms.
6b side length is 90 cms
6c areas 9sq cm and 49 sq cms
6d 11 cms
Answer:
x= 1
QS = 10 cm
QRS = 40cm
Step-by-step explanation:
4x + 1 = 5x
x= 1 cm
QS = 4x + 1 + 5x
= 9x + 1
= 9 + 1
= 10cm
QRS perimeter
QS + RQ + RS but ( RQ = RS)
= 10 + 15 + 15
= 40cm
F(3) = (<span>√3 -7)/6
f(3) = (1.732 - 7)/6
f(3) = 5.268 / 6
f(3) = 0.878 ...nearest thousandths
