Answer:
131
Step-by-step explanation:
(-48)+(-110)+27
Remember one of the most important math rules
- * - = +
-*+= -
+*+ =+
+*-=-
That been said
We can now perform the operation
-48-110+27= -131
I think question statement c is false about proof
The area of a triangle is given by half the multiplication of base and height. Since you want the answer is squared centimeters, let's convert base and height in centimeters first:

Now we can do the computation:

8² (3x -2) + 5 = 56 I do the exponents first
64 (3x -2) + 5 = 56 I distribute the 64 over the 3x-2
192x - 128 + 5 = 56 I combined liked terms (-128+5)
192x -123 = 56 I add 123 to both side
192x - 123 +123= 56 + 123 Finally I divide both sides by 192
<u>192x</u> = <u>179
</u>192 192
x =
