Please help me, I can't understand
2 answers:
check out the document I have uploaded, and the things I have done in blue; that's how you should show the inequality x>5/2
I have colored the right side because x is greater than 5/2, so instead of coloring the left side because if I color the left side it means that x is less but mow you get the inequality as x greater so you should color the side which increases
the left side means that it decreases
(I wanted to help you with the drawing since you already go help with solving and finding the inequality) Have a great day and I hope this helps

Area of a triangle = (1/2)*base*height
For both of the triangles, you have the base (8.8 for the triangle on the left, 7.6 for the triangle on the right) and the side lengths, but not the height. But since both are isosceles triangles, you can find the height using the pythagorean theorem.
5.
First divide the triangle vertically into two triangles (see attached picture). Now you have two right triangles, you can apply the pythagorean theorem on either one of them to find the height. The pythagorean theorem says that for a right triangle, , where c is the hypotenuse and a and b are the sides of the triangle.
Substituting the given values and rounding to nearest tenth:
Now that you have the height, you can find the area of the entire triangle.
A = (1/2)*base*height
A = (1/2)*8.8*9.0 = 39.6
6.
Same procedure.
A = (1/2)*base*height
A = (1/2)*7.6*9.2 = 35.0
