So that gives you
4×5^2-5×3^2
First you have to do the exponents
5^2=25
3^2=9
Now you have 4×25-5×9
4×25=100
5×9=45
100-45=55
55 is the answer.
Answer:
12
Step-by-step explanation:
2 | 6 , 12
2 | 3 , 6
3 | 3 , 3
| 1 , 1
LCM = 2 x 2 x 3 = 12
40
if it takes two workers 10 minutes to plant 3 trees,then it will take 4 workers 5 minutes to plant 3 trees.3÷24=8,then 5×8=40
Answer: Option D
Explanation:
x = input
y = f(x) = output
Table D shows the input x = 2 pair up with the output y = f(x) = 0. But this curve does <u>not</u> cross the x axis. So we can conclude that table D is an incorrect model to represent this curve.
