Answer: The value of x is 3.
Step-by-step explanation:
so we know the surface area of the shape as 112.
And to find the missing angle we could use the equation
20 + 20 + (10 *x) + ( 10* x) +(2 * x) + (2 * x) =112 solve for x and that is x
20 + 20 + 10x + 10x + 2x + 2x = 112
40 + 24x = 112
-40 -40
24x = 72
x= 3
Check: 3 * 10 = 30
3 * 10 = 30
2 * 3 = 6
2 * 3 = 6
2 * 10 = 20
2* 10 = 20
30 + 30 + 6 + 6 +20 +20 = 112
112 = 112
Well i thought it would be C. 9 Meters because Kilometers is really long.
Hope I helped :)
Sorry if was wrong :(
2x + 6y = 14y - 19x^2 + 12 is a non-linear equation
Step-by-step explanation:
Lets define a linear equation first.
A linear equation is an equation in which there is no variable with exponent greater than 1 or the degree of the equation is 1.
So,
<u>x + 12 = -8x + 10 - 2y</u>
The equation is a linear equation because the degree of the equation is 1.
<u>x = 8x + 19 - 10y</u>
The equation is a linear equation because the degree of the equation is 1.
<u>2x + 6y = 14y - 19x^2 + 12</u>
The equation involve a term with exponent 2 which makes the degree of the equation 2 making it a quadratic equation
<u>2x + 13y + 14x - 7 = 16y - 3</u>
The equation is a linear equation because the degree of the equation is 1.
Hence,
2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Answer:
21.25 inches is the width
Step-by-step explanation:
27.5/11 = 2.5 means that the projected image is 2.5 times bigger than the transparency so 8.5*2.5 is 21.25
