2. C : 7×10^5 = 700,000 Viewers

Step-by-step explanation:

1.

a) 6.1×10^6=6,100,000

b) 1.8×10^6=1,800,000

c) 6,100,000+1,800,000=7,900,000

1a) 3.8=X

1b) 4.3×10^6=4,000,000=X

1c) 7.9×10^5=790,000=X

1d) 1.1x10^13=1.1x10^13=X

2.

a) 1.5×10^5=150,000

b) 5.5×10^5=550,000

c) 150,000+550,000=700,000

2a) 3.6=X

2b) 4×10^5=400,00=X

2c) 7×10^5=700,000=!

2d) 8.25x10^10=X

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

it would take 7/10 of an hour too fill the pool.
