Answer:
a. Isosceles + Acute
b. Scalene + Right
Step-by-step explanation:
a. The side markers show that 2 sides are equivalent in length, making it isosceles. The angles are all noticeably under 90 degrees, resulting in it being acute.
b. There are no side markers whatsoever, making it scalene. There is a right angle marker, resulting in the triangle being right.
Answer:
the answer is b
Step-by-step explanation:
1. GCF is a factor that is shared by all terms within a polynomial for example, if we have a polynomial of the form A*B + A*C, the GCF is A since both terms have A as a factor 2. after we factor out the GCF, it is placed outside the parentheses, in front of the rest of the polynomial. using our previous example, A*B+A*C = A(B+C) 3. we can verify that our factoring is correct by distributing the GCF to the polynomial within the parentheses
