You can use the butterfly method. Two numbers that equal A times C must also add up to B. A=1 B=-10 C=21. A times C is 21 and B is -10. Two numbers that multiply to 21 and add to -10 are -7 and -3. Factored form: ( x - 7 )( x - 3 ).
Using the process of dimensional analysis, a method of conversion, 30 ft is equivalent as 10 yards.

ANSWER

EXPLANATION
The point-slope form of a line is given by;

where

is the slope of the line and (6,-1) is point.
We substitute the point and the slope into the formula to obtain:

Hence the b point slope form of the line with the given properties is
Answer:
16
Step-by-step explanation:
Shape C is A trapezoid
Area of trapezoid = 
where a and b = base lengths and h = height
The trapezoid has the following dimensions
base 1 = 3 units
base 2 = 5 units
height = 4 units
Using these dimensions we plug in the values into the formula stated above.

Hence the area of shape C = 16 square units
