Step-by-step explanation:
1) = {5(x+y)} - 2x
= 5x + 5y - 2x
= 3x + 5y
2)= {2(p×q)} + (p×q)
= (2p×2q)+ p×q
= 4pq + pq
= 5pq
3)= 6a + (8b + 2a)
= 8a + 8b
= 8(a+b)
4)= 3x² + ( x²+7x)
= 4x² + 7x
= x(4x+7)
Answer:
in scientific notation, the expression can be written as 6.237 x 10⁶
Step-by-step explanation:
Given;
6.3×10 to the second power times 9.9×10 to the 3rd power
Using scientific notation, it can be interpreted as;
This can be simplified as;
Therefore, in scientific notation, the expression can be written as 6.237 x 10⁶
Answer:
the smaller solid is 121.5
Step-by-step explanation:
It depends on the technology you want to use.
These days, most programs that produce images have a way to set the zoom factor. Changing that changes the scale of the drawing.
When copy machines are used for reducing or enlarging, the scale factor is set to something new by selecting the appropriate enlargement or reduction.
If you're drawing a graph, you change the scale by changing the number of units a grid line represents.
<span>The difference of X and the number is six what is the other number.
Write "the difference between X and another number (Y) is 6." Find Y.
X-Y=6, or Y = X - 6 This is the equation of a straight line. Can't solve this problem for Y without knowing more about X. Ensure that you have copied down ALL of the original problem.</span>
