X=5 I have work shown. hope it helps
Answer:
if i got you question right then its x=(-13/7) x=(-3/(2+b))
Step-by-step explanation:
to find the roots you need to make it equal to 0.
(x+6x+13)(2x+bx+3) =0
(7x+13)((2+b)x+3) =0
now there are 2 cases:
-> 7x+13=0 7x=(-13) x=(-13/7) solved
-> (2+b)x+3=0 (2+b)x=(-3) x=(-3/(2+b)) solved
Answer:
W=30m L=90m
Step-by-step explanation:
A =2,700 m²
L=W+60
we know that area of a rectangle is A=L*W so we sustitute what we know
A=L*W
2,700 = (W+60)*W distribute
2,700 = W² +60W subtract 2,700 from both sides
W²+60W-2,700 =0
solve the quadratic equation with quadratic formula or on the calculator on the graph and will get W= -90 and W=30. Reject the -90 value because we can not have negative measurements. Our solution is W=30
L=A/W=2,700/30=90
The leftmost of the the two digits is 10x that of the right one.
