Answer:

m^{2} + 11m - 11

Step-by-step explanation:

6m+(m-2)(m+7)+3  =   6m   +  [ m*m - 14 -2m + 7m]  + 3

=  6m  + mm - 14 + 5m  + 3

=  mm + 11m - 11

6m+(m-2)(m+7)+3   = m^{2} + 11m - 11

Find an equation of the line that is perpendicular to 9x + 5y = - 1. Write your answer in the form y = mx + b.
Alchen [17]

Answer:

Step-by-step explanation:

move x to the right making the equation 5y=-9x-1 then divide both sides by 5 to get y= -9/5x-1/5. the slope of a perpendicular line is the opposite reciprocal of the slope from the og eq. so the slope of the new line is 5/9x and the y-intercept stays the same so the equation should be y=5/9x-1/5

Express answer in exact form.
Ratling [72]
Area of circle = πr²
= 64π
The cord will subtend a semicircle of diameter 8", radius 4". The area of this semicircle:
1/2 πr²
= 0.5 x 4² x π
= 8π
Area of larger region = area of circle - area of semicircle
= 64π - 8π
= 56π inch²

Explain what it means to bisect a segment. Why is it impossible to bisect a line?
mr_godi [17]
<span>To bisect a segment means to cut through the segment's midpoint. You can't bisect a line, because a line goes on forever = no midpoint. and a line has a width of zero so it is impossibl to bisect it
