Answer:
13 square units
Step-by-step explanation:
You <em>could</em> calculate the length of each side using Pythagorean theorem, then use Heron's formula to find the area. But there's an easier way: find the area of the rectangle that contains the triangle, and subtract the areas of the smaller triangles in the corners.
The area of the rectangle is 4 × 7 = 28.
The area of the upper left triangle is ½(2)(4) = 4.
The area of the upper right triangle is ½(3)(5) = 7.5.
The area of the lower right triangle is ½(1)(7) = 3.5.
So the area of the triangle is:
28 − 4 − 7.5 − 3.5 = 13
Answer:
x = 
Step-by-step explanation:
Given
- 24x - 15 = - 27 ( add 15 to both sides )
- 24x = - 12 ( divide both sides by - 24 )
x =
= 
B right? sorry if i’m wrong i’m not the greatest at math english is my subject
Answer:
24, 48, 72
Step-by-step explanation:
Common Multiples of 8: 8,16,24,32,40,48,56,64,72,80….
Common Multiples of 12: 12,24,36,48,60,72,………..
Hence the First 3 Least common multiple of 8 and 12= 24, 48, 72
