Answer:
i'm guessing you're asking which expression is the same as 7(x+4)
i don't know what the other numbers listed are suppose to mean, but when expanded, 7(x+4)=7x+28
anything added together, multiplied together, etc, that equals 7x+28 is your answer
Answer:
C is correct
Step-by-step explanation:
do you know why? haha
Answer: exponential
Step-by-step explanation:
its exponential
count the squares in each one
first is 2 squares
second is 4 squares
third is 8 squares
this is going up exponentially because the first one would be 2^1 the second would be 2^2 and the third would be 2^3
we know that given terms were i geometric progression.
which means common ratio is same between two consecutive terms .
here we have 8,40,200,1000.
we know that common ratio =second term/first term =40/8=5.
so each and every terms is multiplied by 5 to get next term for this series the term after 1000 is 5000 =1000*5.
in part b we have another series which is having common ratio of -2.
so we need to multiply with -2 to find next term.
80*(-2)=-160.
for part c the common ratio is -2 .
so we need to multiply with -2 *previous term =-2*16 =-32.
The formula for finding the volume of a cube is
, where s is the side length.
The formula for a cube with each side length doubled is
, or 8<span>s.

eight times greater.</span>
