Answer:
6 feet
Step-by-step explanation:
(24+x)(16+x)=660
384+24x+16x+x²=660
x²+40x-276=0
x`= 6
x```= -46......no serve
Answer......is 6 feet

1) Let's evaluate that expression, given that a=4.9, b=-7, and c=-0.5

Note that we have rewritten it as a fraction so that we can easily operate. Also, we have applied here the PEMDAS order of operations, prioritizing the exponents.
Answer:
24.4 Units
Step-by-step explanation:
For this, we will use the distance formula to find the distance between each vertex

So we do this for each side of the triangle to get AB =
, BC =
, and AC = 
We add these all up to get 24.4 (rounded)
Answer : r = 4$
