Can anyone please help me find the length of X?

Alex_Xolod [135]

Solution:

Note that:

2(Perimeter of smaller triangle) = Perimeter of larger triangle

Using the perimeter of the smaller triangle, solve for x.

2(Perimeter of smaller triangle) = Perimeter of larger triangle
=> 2(3.5 + x + h) = 7 + 4 + 2h
=> 7 + 2x + 2h = 7 + 4 + 2h
=> 2x = 4
=> x = 2

The length of x is 2 units.

Solve the inequality 3x - 5 < 4.

Pachacha [2.7K]

Answer:

x < 3

Step-by-step explanation:

Since 3x - 5 < 4 then we can transpose the inequality to make x the subject of the equation:

If 3x - 5 < 4

⇒ 3x < 4 + 5

⇒ x < 9 ÷ 3

⇒ x < 3
