Step-by-step explanation:
Area=(a+b)/2 x h
a=6x+3
b=4x-5
h=-5x+10
Area= -25x^2+55x-10
15/24
4 2/3=(4*3)+2/3=14/3
simply 15/24
15/3/24/3=5/8
refine
5/8*14/3
8 and 14 share a factor of 2
8/2=4
14/2=7
refine
5/4*7/3
5*7/4*3
35/12
convert to mixed number
35/12=2.11
2 11/12
the answer is 2 11/12
Month*
divide 840 with 12
as 1 year has 12 months
and you get 70$
so the family spends $70 every month

Answer: 23</h3>
The three angles of any triangle always add to 180, so,
z+62+95 = 180
z+157 = 180
z+157-157 = 180-157 .... subtract 157 from both sides
z = 23
As a check,
z+62+95 = 23+62+95 = 180
so the answer is confirmed.
