Answer:
1) solve x+1/x = 5
2) solve x³+1/x³
substitute x = 1/4 into the expression
Answer:
Step-by-step explanation:
If you have a square of side 
, its diagonal would be 
, and its area 
If the big square has a area of 900, this implies that its side is 
, so the two diagonal of squares 2 and 4 added together would be , therefore one diagonal wold be 
. and its side 
. The area (of one square) is 
finally the two areas combined (squares 2 and 4) would be 225
Answer:
g(-3) = 1
Step-by-step explanation:
We use the top piece of the function since x = -3
g(-3) = x+4 and x = -3
g(-3) = -3 +4 = 1
<u>Question 2</u>

(HL)
<u>Question 3</u>
1) 
is a right angle, 
(given)
2) 
is a right angle (perpendicular lines form right angles)
3)

7) 
bisects 
(if a segment splits an angle into two congruent parts, it is an angle bisector)
Answer:
Step-by-step explanation:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 5,820
New Number: 5.820
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 8 2 0
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.82 (Please notice any zeroes on the end have been removed)
b = 3
Now the whole thing:
5.82 x 103
Step 4
Check your work:
103 = 1,000 x 5.82 = 5,820
