If you multiply you get 24cm
5 times 6x =30x the second one is 7y+7x the third one is 8x+20y
Answer:
C - fifty-eight fourths
Step-by-step explanation:
The first rule of PEMDAS that applies is exponents. Square roots are considered exponents, as you can rewrite them as exponents. So, first, simplify all of your square roots and exponents.

Then, do your multiplication.
Now, a common mistake is to do division next. But, since there is an addition sign connecting 54 and 4, you must do that operation first. Think of it like:
Thus, your final answer is:
Answer:
I think it is 11 because (-2) squared is 4 and then -2 times -2 is positive 4 so 4+4=8 and then add 3 which equals 11.
Answer:
10 and 11
Step-by-step explanation:
10x10 = 100 and 11x11 = 121. Since 100<105<121, 10<square root of 105<11. So the square root of 105 is between 10 and 11.
