i have asked to someone I'll take some time wait
Answer:
12
Step-by-step explanation:
triangle on left= 2 cuz 2 times 2=4 /2 =2
and same thing with right
then middle it just 2 times 2
ALWAYS REMEMBER DIVIDE THE TRIANGLES BY 2
Without using a calculator I would say the root is between 10 and 11
How I found the answer:
I know 10 * 10 = 100
I know 11 * 11 = 121
So the root of 100 = 10 and the root of 121 = 11 so that means the root of 108 is somewhere between 10 and 11, which the root of 108 = 10.3923
Step-by-step explanation:
Remove the parentheses: 15a²-6ab+8a²+20+5ab-31+a²-ab Combine like terms: 24a²-2ab-11
Answer: 24a²-2ab-11
