what is the value of 7*8?
56
What is the midpoint of the line segment with endpoints (2,3) and (4,7)?
the midpoint is ((2,3)/2,(3+7)/2)=(3,5)
what is the midpoint of the line segment with endpoints (1,2) and (3,4)?
the midpoint is ((1 + 3)/2,(2+4)/2)=(2,3)
what is the distance between the points (1,2) and (4,6)?
using the formula distance: sqrt((4-1)^2 + (6-2)^2=sqrt (3^2 + 4^2) =sqrt (9 +16) =sqrt (25) =5
Sarah has 12 apples. she gives 4 apples to her friend and then buys 7 more apples. how many does she have?

the midpoint is ((-1+3)/2,(-1,+5)/2)=(1,2)
how do you find the slope of a line passing through the points (5,6) and (7,10)?
the slope is (10-60/(7-5)=4/2=2
how do you find the distance between the points (-3,5) and (3,1)?
sqrt (3-(-3)^2+(-1-5)^2

it will travel 60*3=180
solve x in the equation 2x+3=11.
4
what is the midpoint of the line segment with endpoints (0,0) and (6,8)?
the midpoint is ((0 + 6)/2,(0 + 8)/2)=(3,4)
what is the equation of the line with slope 3 passing through the point (2,-1)?
using the point-slope form: y-(-1)=3(x-2) which simplifies to y + 1 = 3x-6, so y = 3x - 7
what what is the distance between (0,0) and (5,12)?
(5-0)^2 + (12 - 0)^2
john has 5 times as many marbles as Tom. if Tom has 8 marbles, how many marbles does John have?
he has 5*8=40 marbles.
what is the area of a triangle with a base of 10 units and a height of 5 units?
25 square units (area = 1/2 * base * height = 1/2 * 10 * 5 = 25)
calculate the midpoint of the line segment with endpoints (-5,2) and (7,-4).
the midpoint is ((-5 + 7)/2,(2,-4)/2)=(1,-1)
what is the distance between the points (1,1) and (4,5)?
he distance is sqrt ((4-1)^2 + (5-1)^2 = sqrt (3^2+4^2) = sqrt (9 + 16)= sqrt (25) = 5
calculate the distance between the points (-2,-3) and (3,7).
sqrt (3-(-2)^2 + (7-(-3)^2
