Answer:
see explaination
Step-by-step explanation:
length (l) = 2x+7
width (b) = 9x
area of rectangle = l×b
=(2x+7)(9x)
=18x^2+63x
perimeter of rectangle = 2(l+b)
=2(2x+7)(9x)
=2(18x^2+63x)
=36x^2+126x
-3 is a solution
4x+2 < -6
subtract 2 from each side
4x < -8
divide by 2
x < -2
Answer: No solutions
a = v-u/t
2 = 20 - u / 5
10= 20-u
u = 10 m/s
RS=26.49 m;
ST =14.08 m;
m<R =28°
