Answer:
6.
Step-by-step explanation:
4+2 = 6 lol hehehehehe
Answer:
1.64×10⁷ km
Step-by-step explanation:
We know this is a triangle rectangle, so we apply the Pythagorean Theorem
QR=sqrt(PR²+PQ²)
Solving it, we will encounter in
sqrt(2.56×10¹⁴+1.296×10¹³)
to solve it, we need to bring the two numbers at the same power of ten, so we move 1.296 of one place to the left:
sqrt(2.56×10¹⁴+0.1296×10¹⁴)
we can now add the two numbers:
sqrt(2.6896×10¹⁴)
to solve this, we do the square root of 2.6896 and divide 14 by two (the index of the root is 2, so for roots' properties we can divide 14 by 2 - the index)
which gives us
1.64×10⁷
Answer:
26.37
Step-by-step explanation:
Apparently, we're to substitute 9 for 4 and recompute:
26.37 = (2.93)9
____
This assumes that the 4 in the expression is the number of boxes, and the (2.93) in the expression is the price per box. The product of those numbers is 11.72, apparently the total cost of 4 boxes of nails.
Answer:

Step-by-step explanation:
<em>Step 1: Consider the assumption:</em>
Generally,
) is supposed to be the pair of 2 components, in which, the first component is x-component (domain), the second component is y-component (range).
Hence, 
<em>Step 2: Substitute </em>
<em> and </em>
<em> into the inequality</em>

<=> 
<em>Step 3: Simplify</em>
<=> 
<=> 
<em>Step 4: Evaluate</em>
Invalid
Reason: 
<em>Step 5: Conclude</em>
is not a solution to the inequality 
Hope this helps!
