You might need to use the distance formula
for the distance betwen (x1,y1) and (x2,y2) is
so find disance between (-3,1) and (-1,3)
and (-1,3) and (3,1)
so
if we did input them
we would get
which is the peirmiter

Answer:
-7 or 4
Step-by-step explanation:
use foil to get the quadratic equation:
x^2+5x-2x-10=18
x^2+3x-10=18
bring "18" to the left:
x^2+3x-10-18
x^2+3x-28
so what*what= -28
and
what+what=3
factors of -28: -7,4 -4,7 14,-2 -14,2 -28,1 -1,28
factors whose sum is 3: 7,-4
so substitute "7,-4" in place of 3:
x^2+7x-4x-28
2) split it in two groups
group 1) x^2+7x
group 2) -4x-28
x^2+7x has a GCF of "x"
x(x+7)
group 2) -4x-28 has a gcf of "-4"
-4(x+7)
3) (x-4) (x+7)=0
x-4=0
x=4
x+7=0
x=-7
x=4,-7
Hope this helps!
Answer:
p = 42
area = 72
Step-by-step explanation:
p = 3 + 9 + 12 + 5 + 9 + 4 = 42
area:
3 × 4 = 12
5 × 12 = 60
12 + 60 = 72
