Answer:
Factor x2 + 9x + 18.
A) (x - 3)(x - 6)
B) (x + 2)(x + 9)
C) (x + 3)(x + 6)
D) (x - 2)(x - 9)
Step-by-step explanation:
(x+3)(x+6)=x^2+6x+3x+18=x^2+9x+18
Given:
Trapezoid with bases 10 and 20, and height of the trapezoid is 6.
To find:
The area of the trapezoid.
Solution:
We know that the area of a trapezoid is:
Where, h is the height of the trapezoid and 
are bases of the trapezoid.
Putting 
in the above formula, we get
The area of the trapezoid is 90 sq units. Therefore, the correct option is A.
The answer is 3.75 or 15/4 or 3 3/4
Write a system of equations and solve.
x + y = 10
5x + 10y = 90
Multiply and combine equations
-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2
There are 2 nickels and 8 dimes in the jar. Hope this helps! :)
X = 4 because 1 over 24 times 4 is 4 over 24 which is converted to 1 over 6
