Answer:
The answer could be either 10 or -7
Step-by-step explanation:
(w-3)(w)=70
w^2 -3w=70
w^2 -3w-70=0
(w-10)(w+7)=0
w=10 or -7

Answer:
The perimeter of the triangle is equal to 36 cm
Step-by-step explanation:
we know that
The inscribed circle contained in the triangle BCA is tangent to the three sides
we have that
BF=BH
CF=CG
AH=AG
step 1
Find CG
we know that
CF=CG
so
CF=7 cm
therefore
CG=7 cm
step 2
Find AG
we know that
CA=AG+CG
we have
CA=15 cm
CG=7 cm
substitute
15=AG+7
AG=15-7=8 cm
step 3
Find AH
Remember that
AG=AH
we have
AG=8 cm
therefore
AH=8 cm
step 4
Find BF
Remember that
BF=BH
BH=3 cm
therefore
BF=3 cm
step 5
Find the perimeter of the triangle
P=AH+BH+BF+CF+CG+AG
substitute the values
P=8+3+3+7+7+8=36 cm
Step-by-step explanation:
c+22=c+2
3+22=3+2
25=5 not true.
(-6)+22=(-6)+2
28=8 no true.
c+22=c+2
(-6)+22=3+2
28=5 ther is no equal
