Answer:

A

Step-by-step explanation:

Note: I suppose you typed the question wrong, thus I calculated the question in the picture

x =  \frac{ - b +  -  \sqrt{{b}^{2}  - 4ac}  }{2}  \\  =  \frac{5 +  -  \sqrt{25 - 4 \times  - 2 \times 1} }{2}  \\  =  \frac{5 +  -  \sqrt{25  + 8} }{2}  \\  =  \frac{5  +  -  \sqrt{33} }{2}

Write the slope-intercept equation of a line parallel to y = 3x + 2 that
AURORKA [14]
Parallel lines have the same slope, in this case 3.

To find the y intercept we plug in the points (2,1) into y=mx+b, with 2 being x and 1 being y.

1=3(2) + b
Solve this and you get -5 as the y intercept.

The equation is y=3x-5

4+8x(18+5)+18+(8x4x5)+0x(5+3)=
Natasha_Volkova [10]

The Mathematical statement which includes addition, subtraction and multiplication:

→4+8x(18+5)+18+(8x4x5)+0x(5+3)

= 4 + 8 × 18 + 8 × 5 + 18 +(32 × 5) + 0 × 5 + 0 × 3  → [ Using distributive property which is , a × (b +c)= a × b + a × c, and (p × q × r)= [ (p × q) × r]

= 4 + 144 + 40 + 18 + 160 + 0 + 0  

=  148 + 58 + 160  → [ Using addition property of natural numbers, as you can add natural numbers in any order]

=  206 + 160

=  366

Bess [88]

Answer:

311.25 hours ; almost 13 days

Step-by-step explanation:

actually you will not able to drive a car all the way around the earth (the Pacific and Atlantic oceans are really big).

but According to the calculation it would take you around 311.25 hours ( almost 13 days) to drive the 24,900 miles around the circumference of the earth at its widest point (the equator).

because we know ,

t=s/v

 =(24,900/80)hours                    [ s= the circumference of the earth]

 =311.25 hours                              [v=Velocity]
