Answer:
3.1 x 10^9
Step-by-step explanation:
(2.8 x 10^9) + (3 x 10^8) = (28 x 10^8) + (3 x 10^8)
= (28+3) x 10^8
= 31 x 10^8
= 3.1 X 10^9
Answer:
y=27
Step-by-step explanation:
We know that area of rectangle its equail A=l*w.
We know that length is 4 times greater than width, so we can say
l=4x and w=x
Knowing that area A=144 we can say
4x*x=144
-
w=6 - its the width
l=6*4=24 - its the length
