Answer:
15
Problem:
Given that a*b = 2ab - 3b. Determine 2*(3*5)
Step-by-step explanation:
First we find 3*5 using rule a*b = 2ab - 3b.
3*5=2(3)(5)-3(5)
3*5=30-15
3*5=15
Now we are left with 2*15 in which we will still use the rule a*b=2ab-3b.
2*15=2(2)(15)-3(15)
2*15=60-45
2*15=15
Therefore, 2*(3*5)=15.
Answer:
30cm
Step-by-step explanation:
First I added 6 and 13 to get 19 then i said that they were going straight down to measure the sides so that means you need to multiply 5 times 2 and get 10 but the sides are tilted so if the sides are tilted then you need to add a half more for each because they are actually a little bit bigger then what they are saying so now you have 5 1/2 plus 5 1/2 and that gets you to 11 and 11 plus 19 is 30
hope this helps!
