To do this we take the outlier off the parenthesis (the 4) and multiply it by the two numbers inside the parenthesis...
4*7 + 4*8
28+32
Answer:
x=43°
Step-by-step explanation:
The angles are adjacent and create a straight line so their sum is 180°.
(x+6)°+(3x+2)°=180°
x°+6°+3x°+2°=180°
4x°+8°=180°
4x°=172°
x=43°
Answer:
A = 100 
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A = 
(a + b)
Now, substitute the values of the height and the bases:
A = 
(10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100
Answer:
53 in.^2
Hope that helps!:)
No it isn't.
Explanation:
x/y * y = (y-6) * y
x = y^2 - 6y
A function gives just one y for every x
In this case there will always be 2 y's for every x
Example:
y can be
y = 6
or
y =−6
(0,-6) & (0,6)
