Question

can anyone please help me please​

Answer 1

Answer:

1. by replacing z with 3 in the equation,we get,

4z^2 -z-3=30

2.3x=12-6

3x=6

x=6/3

x=2

3.c)transversal

4.100+angleC= 180°

angleC=80°

by angle sum property,

A+B+C= 180°

40+80+B=180

120+B=180

B= 60°

5.a) 1386cm^2

as,

area=πr^2

=(22/7)×21×21

=22×3×21 ( 3×7=21, therefore it is cancelled)

=1386 cm^2

hope this helps you! pls mark me as brainliest!
