$86 is she spending on the party.
Step-by-step explanation:
As per the statement: A company employee is planning a promotion party with her friends. She orders 6 pizzas for $7 each, 2 bowls of mixed salad for $12 each, and 4 cases of assorted soft drinks for $5 each.
⇒ 6 pizzas for $7 each
Total cost for 6 pizzas =
2 bowls of mixed salad for $12 each.
Total cost for 2 bowls =
and
4 cases of assorted soft drinks for $5 each.

She spending on party = Total cost for 6 pizzas + Total cost for 2 bowls + Total cost for 4 cases of assorted soft drinks
Substitute the values we get;
Total cost she spending on party =
<span>You can use Heron's formula to solve this problem.

, where A is the area; a,b,с are the sides; s<span> is the </span>semiperimeter<span> of the triangle
</span>
<span>According to conditions:
</span>a = x
b = x+1
с = 2x-1
<span>Calculate the semiperimeter:
</span>
<span>Now we can compose and solve the equation according to Heron's formula:
</span>
<span>As a result, x = 6 is your answer.
