The product of two numbers a and x is b. what operation is the used to solve the equation that represents this statement for the value of x
a)add a to each side
b)subtract a from each side
c)multiply each side by a
d)divide each side by a

What number should be added to both sides of the equation to complete this square? x^2-10x=7

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

What are the solutions of the system? solve by graphing. y = -x^2 - 3x + 2 y = -2x + 2
