Help me with this question

Pretty sure its 7.5 units²

Step-by-step explanation:

5·3=15÷2=7.5

Doing area with triangles is kind of the same as rectangle, just do base × height. But then divide it by two.

For example: base=3, height=7. With rectangles it would be 21 units².

But with triangles it would be 3·7=21 divided by 2, it would be 10.5 units²

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
