Answer: 16
Step-by-step explanation:
an area is always calculated by multiplying 2 dimensions.
when changing the dimensions, then the change factors for EACH dimension go into the calculation too.
therefore, when both dimensions of an area are enlarged 4 times, then the area is enlarged 4×4 = 16 times.
this just propagates to the whole surface area of an object, as each individual area of the overall surface area is enlarged by the same factor. and so, the sum of all the individual areas (= altogether the surface area of the object) is also enlarged in total by the same factor.
just think
16×a + 16×b + 16×c ... = 16×(a+b+c+...)
Answer:
D
Step-by-step explanation:
First of all, a very easy way is to count all the rectangles and then count the squares that are shaded and have balloons.
You'll get 7 squares that are shaded and have balloons and 16 rectangles in total.
So the fraction will be 
Another simple way is to just multiply 
and 
Answer:

The formula of a continuous compound interest is
A=p e^rt
A future value 7300
P present value 1500
E constant
R interest rate 0.0675
T time?
Solve the formula for t
T=[log (A/p)÷log (e)]÷r
T=(log(7,300÷1,500)÷log(e))÷0.0675
T=23 years
Answer: y because it’s always easier to get the equation into y=Mx+b form
