Answer:
The expression was rewritten using the associative property. (6·3) · 2 equals 18 · 2, which equals 36.
6 · (3·2) equals 6 · 6, which equals 36.
Ok the surface area is 2lw+ 2lh + 2wh because that is the sum of all the surfaces
You get 96 + 96 + 72 mm^2
We can proceed in solving the problem since all information are given such as 2*4*5costheta.
we have a=4, b=5, and C=theta
let us solve for "c" using Pythagorean
c²=a²+b²
c²=4²+5²
c=6.4
Solving for theta or C
c²=a²+b²-2abcosC
6.4²=4²+5²-2*4*5*cosC
C=90
In this question , we have to use compound interest formula, which is

Here Amount after 3 years = $133.10
Rate of interest = 10%=0.1
TIme =3 years
So we get

Now we have principal, P = $100,
Rate of interest, r =0.1
Time, t = 5 years
So we will get

So the balance after 5 years will be $161.05 .
