Since this is an isosceles triangle, then the lengths of both legs are equal
Therefore,
x+1=-x+7
2x=6
x=3
Therefore, the length of the base is:
3x-3=3(3)-3=6
Then your answer is (A)
Answer: 32 Cm squared

Step-by-step explanation:
Answer: y=2x-3
Step-by-step explanation:
divide both sides by 7
7y/7=(14x-21)/7
y=2x-3
