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

Answer:
the area is 20 in
Step-by-step explanation:
3 times 4 is 12. since we used 3 inches out of the 11, we can only multiply the 8 inches with 1. 8 times 1 is 8. 12+8=20.
Find the highest common factor
12 = 1, 2, 3, 4, 6, 12
24 = 1, 2, 3, 4, 6, 8, 12, 24
28 = 1, 2, 4, 7, 14, 28
4 bags is needed
3 apple, 6 blueberry, 7 banana in each bag
(3 x 4 = 12 apple) (6 x 4 - 24 blueberry) (7 x 4 = 28 banana)
Answer: -64z
Step-by-step explanation: I assume you mean the 2 is an exponent, so -8z x -8z = -64z.
