Answer:

11 units

Step-by-step explanation:

Since ∆ABC is isosceles, it means that at least two sides are congruent/equal in length.

Sides CA and AB are congruent, since BC is the base. So, CA = 4.

That means the perimeter is 4 + 4 + 3 = 11 un

Here is a linear equation: y = 10+ 1. Are (1,1.5) and (12, 4) solutions to the equation? Select the correct choice.

Yuki888 [10]

Answer:

[see below]

Step-by-step explanation:

Assuming that the equation is y = 10x + 1

(12, 4)

4 = 10(12) + 1

4 = 120 + 1

4 ≠ 121

(12, 4) is not a solution.

(1, 1.5)

1.5 = 10(1) + 1

1.5 = 10 + 1

1.5 ≠ 1

They are not solutions to the equation.

Hope this helps.
