Answer:
the integer is 5
Step-by-step explanation:
x^2+3(x+1)=43
x^2+3x+3=43
x^2+3x+(9/4)=43-3+(9/4)
(x+(3/2))^2=42 1/4
x+(3/2)=sqrt(42 1/4)
x+(3/2)=6 1/2
x=(6 1/2)-(3/2)
x=5
check:
5^2+3(6)=43
25+18=43
43=43
<span>10r^2 − 11r − 6 = (2r - 3)(5r +2)
so
A = </span>(2r - 3)(5r +2)<span>
as you know A = L * W
if width = </span>(2r - 3) then length = (5r +2)
answer
length = (5r +2)
