The simplified mathematical expressions with the first factor to the nearest tenth are:
7.8 x 10
3.3 x

3.7
<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x
) . (9.1 x
)
= (8.6 x 9.1) x
= 78.26 x
= 7.8 x 10
(6.9 x
) . (4.8 x
)
= 33.12 x 
3.3 x 
(3.7 x
) . (4.6 x
) ÷ (1.4 x
) . (5.7 x
)
= 1.7 x 10 ÷ 8 x10²
0.21 x 
2.1 x 
(3.1 x
) . (5.3 x
) ÷ (7.3 x
) . (6.1 x
) = 3.7

Answer:
x = 8
Step-by-step explanation:
For this question, you can use power of a point, more specifically when two secants intersect in the interior of a circle. From this, you get the equation:
(7 + x)(12) = (10)(2x + 2)
You can simplify and solve:
84 + 12x = 20x + 20
84 = 8x + 20
64 = 8x
x = 8

multiply 244 and 3.2 and you get D. hope this helps.
Answer: no solution
Step-by-step explanation:
They have the same slope which means they are parallel lines that will never cross or intersect. This mean that there is no solution
