If the perimeters of each shape are equal, which equation can be used to find the value of x? A)(x+4)+x+(x+2)=1/2x+(x+3) B)(x+2)+x+(x+4)=2(1/2x)+2(x+3) C)2 (x) + 2 (x + 2)=2(1/2 x) + 2(x+3) D)x + (x + 2) + (x + 4) =2 (x + 3 1/2)

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?

If two parallel lines are cut by a transversal, interior angles on the same side of the transversal are supplementary. a. always b. sometimes c. never
