Solve the perimeter formula for an isosceles triangle, P = 2a + b for a. a = P + 2b

a = P – 2b

Step-by-step explanation:

subtract b to get P-b=2a. divide each side by 2 to get (P-b)/2=a

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
