Answer:
x = ±2
Step-by-step explanation:
9x^2-36=0
Using the square root property
9x^2 = 36
Divide each side by 9
x^2 = 4
Take the square root of each side
sqrt(x^2) = sqrt(4)
x = ±2
2 / 15 = 30 / x.....2 inches to 15 miles = 30 inches to x miles
could also be :
15 /2 = x/30...15 miles to 2 inches = x miles to 30 inches
either way, u will get the same answer

Answer:
x=8
NR=5 units
BI=10 units
Step-by-step explanation:
In a rectangle BRIA
AN=5 units
NR=x-3
We have to solve for x , NR and BI.
We know that
Diagonals of rectangle bisect to each other.
BI and AR are the diagonals of rectangle BRIA and intersect at point N.
AN=NR



Substitute the value of x
NR=8-3=5
By property of rectangle
BI=AR=AN+NR=5+5=10 unit
BI=10 units
