Answer: x= 0.3 or x=3/10
Step-by-step explanation:
90x=27
divide both sides by 90
x=27/90 which simplfiyes to 3/10
x=0.3
Answer:

Step-by-step explanation:
In this case, the <em>y-intercept</em><em> </em>and <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] are given to us, so just put it in Slope-Intercept Form:

If you want it in <em>Standard Form</em>:
y = 4x - 21
- 4x - 4x

By using the general equation for a circle, we will see that the correct option is:
(x - 2)^2 + (y - 3)^2 = 36

How to find the equation for a circle?</h3>
The general equation for a circle centered at the point (a, b) of radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
In this case, the center is (2, 3) and the radius is R = 6 units, replacing that in the above equation we get:
(x - 2)^2 + (y - 3)^2 = 6^2
(x - 2)^2 + (y - 3)^2 = 36
So the correct option is B.

Answer:
33cm
Step-by-step explanation:
area of a rectangle= length ×width
Let x be the length
990=x( x-3)
990=x^2-3x
x^2-3x-990=0
x^2+30x-33x-990=0
x(x+30)-33(x+30)=0
(x-33)(x+30)=0
x=33, x=-30
length is positive so it'll be 33cm
