Algebra is the devil's arithmetic. I had to repeat it twice bc my teachers were either too lazy to teach it or humilated me.
Answer: 24 or 28
Step-by-step explanation:
√a² + 12 + b
√(-2)² + 12 + 14
√4 + 26
-2+26=<u>24</u>
2+26=<u>28</u>
24 or 28
Group like terms and factor
group the ones with 8 together and the rest apart
(x²+xy)+(-8x-8y)
factor
x(x+y)+(-8)(x+y)
factor out (x+y)
(x+y)(x-8)
Answer:
x=4
Step-by-step explanation:
2(8 - 12x) + 8x = -25x + 52
Distribute
16 -24x +8x = -25x +52
Combine like terms
16 - 16x = -25x +52
Add 25x to each side
16 -16x+25x = -25x+52+25x
16+9x = 52
Subtract 16 from each side
16+9x-16 = 52-16
9x = 36
Divide by 9
9x/9 = 36/9
x =4
Answer:
2,500
Step-by-step explanation:
<h3><u>Place value , rounding </u></h3>
the place values of the number 2,472 is :
2 ---- thousands
4---- hundred
7--- tens
2--- units
when rounding off to the nearest hundreds we look at the 4 ( hundred ) and the value after it which is the 7 ( ten)
if the number in the (tens) position is greater than 5 , the number would be rounded up . else if it is lower than 5 it would be rounded down.
in this case the number in the tens position is 7 hence it is rounded up hence 2,472 becomes 2,500
<h3>hence the number 2,472 to the nearest hundred is: 2,500</h3>
