Answer:
A = 25
Step-by-step explanation:
Base = |-2-(-7)| = |-2+7| = 5
equation of the line that includes the base
x = 6 (because it is parallel to y axis)
the height passes to the point (-4,-4) and must be perpendicular to the base
the equation of the line of the base hasn’t the slope expressed, so the line of the height has a slope equal to 0
so the equation of the line is y= -4
the point (6,-4) is where the two lines intercept and it is the point where the height hit the base
height = |-4-6| = 10
A = (base x height)/2 = (5x10)/2 = 25
Answer:
k=3
Step-by-step explanation:
Move k over to the 2k side and 2 to the five 5-2=3 and 2k-k=k
k+2=5
k=3
Answer:
398in2
Step-by-step explanation:
Surface area formula for a rectangular prism = A = 2(wl + hl + wh)
2(width*length)(height*length)(width*height)
L= 9
W= 5
H= 11
A=2(wl+hl+hw)=2·(5·9+11·9+11·5)=398
