5. A
6. No, 1/5(25x+15)-7x= -2x+3
-2(x-5)= -2x+10
-2x+3 is not equal to -2x+10
The answer to this problem is C.
Here's why:
The area of a triangle = 1/2 * (base) * (height) (Note: a triangle is half of a rectangle, and rectangles have Area = (base) * (height))
<span>Because the base of ΔAED is half of ΔACB (2 = (1/2) * 4), and height of ΔAED is half of ΔACB (3 = (1/2) * 6), we know that the area of ΔAED will be half of ΔAED.
</span>
So, it's C. I am sure =)
If it helped you, please mark me brainliest! =D
Have a nice day!
1,2, 3, 4, 5, 6, 10, 12, 15, 20, 30 and 60.
