Yes.
To form a triangle every side must be smaller in length than the sum of the two other sides.
For example: sides denoted by a,b,c
for a triangle to form
a<b+c
b<a+c
c<a+b
Thus in the case of the <em>Isosceles </em>triangle with side lengths 1,8,8 the rules aforementioned are fulfilled. This means that a triangle with said side lengths can exist.
Answer:
x<2
Step-by-step explanation:
3x +12<18
collect like terms
3x <18 -12
3x<6
divide through by 3
x<2
2×+7=27
2×-7=27-7
2× =20
2/× =20/2
× = 10
2(10)+7=27
3×+1=28
3×-1=28-1=27
3× =27
3/× =27/3
× =9
3(9)+1=28
27 does not equal 28
so no
Since it's a square, all sides are equal
therefore,
3x - 5 = x + 1
2x = 6
x = 3
sub x into AD, which is 3x-5
= 3(3) - 5
= 9 - 5
= 4
therefore AD is 4 units
Your answer is $2
