Answer:
x=145
Step-by-step explanation:
simply subtract 35 from both sides, so you can isolate the variable. once done, you will get that x=145
Answer:
x^3(2x+1)(2x-1)
Step-by-step explanation:
first take common then use formula of a^2-b^2
Answer:
64
-8 to the second power is -8^2 Which is -8×-8 Which gives 64
Answer: Choice 2) A, B, C
====================================
Explanation:
Use a calculator to find that,
- 946/32 = 29.5625
- 1157/11 = 105.1818 approximately
- 3524/44 = 80.0909 approximately
- 37392/82 = 456
The first three results have a decimal portion as the answer. So there is a remainder here. The remainder is the leftover bit that couldn't make another full value. Only choice D results in a whole number that isn't a decimal value, so this does not have a remainder.
As a smaller example, let's say we had 20 cookies and 3 people. If we want to divide the cookies evenly, then each person gets 20/3 = 6 full cookies and there would be 2 cookies left over (6*3 = 18 are eaten so 20-18 = 2 is left over). Notice that 20/3 = 6.67 approximately. The non-whole number decimal value indicates we have a remainder. If we had 21 cookies, then each person gets 21/3 = 7 full cookies with nothing left over, so there's no remainder here.
