Yes she does have enough here's my work
16 times .20 equals 3.2 and the add 3.2 to 16 and get $19.20
40x - 2 because you combine like terms so it's 40x and then combine 8 and -10
Answer:
1.) D
2.) 12in
3.)6
Step-by-step explanation:
One way is factor
exg
if you wanted to find the square root of 36 you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6
so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81
the answer is a little more than 8
the more exact one would be from a calculator (8.0622577482985)
