Answer:
10x+15
Step-by-step explanation:
area of the two rectangles combined is one big rectangle
area of rectange= base*height
base length: 2x+3
height: 5
(2x+3)*5
=(2x*5)+(3*5)
=10x+15
1 g/ml is 8.3454 lbs/gal. So you multiply 1.09 into 8.3454 and your answer is 9.1 lbs/gal
Vsphere=(4/3)pir^3
when we replace r with 2r
newvsphere=(4/3)pi(2r)^3
newvsphere=(4/3)pi8r^3
newvsphere=8((4/3)pir^3)
newvsphere=8(vsphere)
it's volume is multipliied by 8
that is choice C, because 2^3=8, it's vollume is 8 times original voluem
answer is C
The answer for number 6 will be C, and the answer for number 7 will be D. Hope it help!
