A=1/2bh
b=8+h
A=384
384=1/2(bh)
times 2
768=bh
sub
768=b(8+b)
768=8b+b^2
minus 768 both sides
0=b^2+8b-768
factor
0=(b-24)(b+32)
set to zero
b-24=0
b=24
b+32=0
minus 32
b=-32
false, legnths cannot be negative
b=24
24=8+h
minus 8
16=h
base=24ft
altetude=16ft
Answer:
1/23
Step-by-step explanation:
The perpendicular slope will be the opposite reciprocal of the original slope so if slope of c is -23, slope of d is 1/23
Answer:
y=-5x+7
Step-by-step explanation:
Prallel lines have the same slope
so the slope of the unknown line is -5
and passes through(1,2)
y-2=-5(x-1)
slope-intercept form:y=-5x+7
