Answer:

11 units

Step-by-step explanation:

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

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

That means the perimeter is <em>4 + 4 + 3 </em>= 11 un

Svetach [21]
What we know:
Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 7 liters of natural oil for every 5 liters of synthetic oil.

What we need to find:
If 355 liters of synthetic oil are used, how many liters of petrolyn oil will be made?

Set up a proportion to find how much natural oil is used.
7L natural oil/5L synthetic oil = x/355 synthetic oil where x=natural oil
7/5=x/355
(5)(x)=(7)(355) cross multiplied
5x=2485 simplified
5/5x=2485/5 multiplicative inverse
x=497L

Now, add both synthetic oil and natural oil to find amount of petrolyn oil.

355 L synthetic oil + 497 L natural oil= 852 L of petrolyn oil
