14) The perimeter of this isosceles triangle is represented by the
Galina-37 [17]

The isosceles triangle is missing so i have attached it.

Answer:

Length of unknown side = 5p + 6

Step-by-step explanation:

In isosceles triangle, two of the sides are equal. In the attached triangle, we see that one of the equal sides is given as 5p + 3.

Thus,the second equal side is also 5p + 3.

Now, perimeter of a triangle is the sum of the three sides.

We have two sides and let the third side be denoted as x.

Thus;

Perimeter = (5p + 3) + (5p + 3) + x

We are given perimeter = 15p + 12

Thus;

(5p + 3) + (5p + 3) + x = 15p + 12

10p + 6 + x = 15p + 12

Rearranging, we have;

x = 15p - 10p + 12 - 6

x = 5p + 6

Need help with number 7
tatyana61 [14]

Since she runs 6\frac{1}{2} miles each day and there 7 days per week, you will have to multiply 6\frac{1}{2} times 7.

But since you have to use distributive properties, multiply like this (6\frac{1}{2})(7)

6\frac{1}{2} is equal to \frac{13}{2}

Now turn 7 into a fraction, so its \frac{7}{1}

Now multipy (6\frac{1}{2})(\frac{7}{1})

Multiply the numerators, so its 7 * 13 which gives you 91 and multiply the denominators so its 1 * 2 which gives you 2.

Put that back into a fraction as \frac{91}{2}

Divde it to change it to a mixed number and the answer is 45\frac{1}{2}
