X = 42 and y = - 23 are the two numbers
The side length is about 17.916
Answer: 600 ft.
Step-by-step explanation:
The height is 12, and the base is 50. So V=ABh=50·12=600ft³, just plug in the numbers.
I think it’s 9 x (-7)(2) which equals -126
Rectangle's Perimeter is P=2(w+l)
where w and l are width and length respectively
34=2(w+l)
17=w+l
w=17-l
now A=wxl
A=(17-l)xl
A=17l-l^2
30=17l-l^2
l^2-17l-30=0
now solve for l
