Answer:
Perimeter= 44.2 inches
Area= 70 inches squared
Step-by-step explanation:
Perimeter- Add all your sides together (10+ 17.2+2+3+7+5=44.2)
Area- 1/2bh (b=base, h=height)
Your base is the bottom of the triangle, so 2+7+5=14.
14 is your base
Your height is the 10
1/2 *14*10
1/2 of 14 is 7
7*10= 70
Don't forget to write inches squared or it will be wrong
Hope this helps :)

=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.
Answer:
x = 704/39 ( <----Fraction)
Step-by-step explanation:
28 squared minus 39x minus 80 equals 0
784-39x-80=0 evaluate the power
704-39x=0 Subtract the numbers
-39x=-704 move the constant to the right hand side and change it's sign
