Perimeter of Triangle -:
( 3.7 b + 1.7 +1.3b +1.1 + 7.1 c + 5.1 )
now solve by ur self
140x 0.3= 42
140- 42= 98
So A. $98 is correct.
Answer:
118 i think
Step-by-step explanation:
-2{-7-2[3 squared + 2 to the power of 4]-8÷4}
-2{-7-2{9+16]-2}
-2{-7-50-2}
-2(-59)
118
Answer:
The top of the ladder is now at 10 ft.
Step-by-step explanation:
At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

The base is moved twice the distance the height moves up.
We called this distance x, so we have:

The new height (H+x) is

The base travels 2x=8, so the new base B' is 0.
This means that the ladder is all against the wall (L=H').
I think it would be the third option. I jiust guessed.
