x = 5 and y = 6

Solution:

IJKL is a rectangle.

<em>In rectangle, opposite sides are equal.</em>

JK = IL

3x + 21 = 6y

Subtract 21 from both sides.

3x = 6y – 21

Divide by 3 on both sides, we get

x = 2y – 7 ---------- (1)

<em>In rectangle, opposite sides are equal.</em>

JI = KL

6y – 6 = 2x + 20

Substitute (1) in above equation, we get

6y – 6 = 2(2y – 7) + 20

6y – 6 = 4y – 14 + 20

6y – 6 = 4y + 6

Subtract 4y from both sides.

2y – 6 = 6

Add 6 on both sides.

2y = 12

y = 6

Substitute y = 6 in (1)

x = 2(6) – 7

x = 5

Hence x = 5 and y = 6.

Answer:

Option B: 3x + 3y - 3

Step-by-step explanation:

In an isosceles triangle, the two congruent sides are equal.

We are told the base is; x - y - 2 units

Now let each of the congruent sides be represented as A.

Thus the perimeter equation will be;

P = 2A + x - y - 2

Now, we are told that the perimeter is; 7x + 5y - 8 units

Thus;

7x + 5y - 8 = 2A + x - y - 2

Rearranging gives;

7x - x + 5y + y - 8 + 2 = 2A

2A = 6x + 6y - 6

Divide through by 2 to give;

A = 3x + 3y - 3 units
