Hope I can help you, brainliest answer? :)
Step-by-step explanation:
1.

2.

First equation: Your equation is given.
Second equation: Distribute by multiplying every number in the parentheses by the number outside it.
3rd equation: Combine like terms by adding 4x to both sides.
4th equation: Combine like terms by subtracting 14 from both sides.
5th equation: Divide both sides by -2, the coefficient of x.
Answer:
The perimeter of the triangle is about 17.1 units.
Step-by-step explanation:
The perimeter of a triangle is the sum of its three side lengths.
We can see that the two legs of the triangle both measure five units.
To find the third segment, we can use the Pythagorean Theorem since the <em>x-</em>axis is perpendicular to the <em>y-</em>axis. Recall that:

Where <em>a</em> and <em>b</em> are the two legs and <em>c</em> is the hypotenuse.
Our two legs are 5 and 5. Hence:

Solve for the hypotenuse:

Hence, our perimeter will be:

In conclusion, the perimeter of the triangle is about 17.1 units.
t - 11
Set up the equation using some key words, 11 less than a number means that 11 is being subtracted from the number, which is t, a variable.
