Question

PLEASE HELP URGENTLY. Look at the given triangles.

Two triangles are shown

The blue triangle is a right triangle. The vertical leg is labeled with the expression 4 x plus 2. The horizontal leg is labeled with the expression 5 x minus 4. The hypotenuse is labeled with the expression 7 x plus 7.

The red triangle is a right triangle. The vertical leg is labeled with the expression x plus 3. The horizontal leg is labeled with the expression x plus 7. The hypotenuse is labeled with the expression 2 x minus 5.


a. Write an expression in simplest form for the perimeter of each triangle.

b. Write another expression in simplest form that shows the difference between the perimeter of the larger triangle and the perimeter of the smaller triangle.

Answer 1

Explanation:

blue: 4x+2+7x+7+5x -4 = 16x +5

red: x+3+x+7+2x-5 = 4x -5

difference: 16x+5 - (4x -5) = 12x +10
