A) -3.5*2^2*3=-14*3=-42
c) -3*y*z^2=-3*(-4)*3^2=12*9=108
6x*y^2=6*2*(-4)^2=12*16=192
P=2*(108+192)=2*300=600
b) 5/2*(-4)^2=5/2*16=40
Answer:
12.5% Decrease
Step-by-step explanation:
(10/80)*100
1/4 ….
you do 3-2 which is 1
then you do 3- -1 which is 4
It would be lesser than because 1 × any number is that number so if you multiply by anything less then 1, you'll get something less then the number you started with.
Ex: 5 × 1/4 = 1 1/4
9 or 3^2 is HCF, all common factors are 1, 3, and 9 or 3^2
