What is 1+1+1+1+1+1+1-8+1+8+10+20+8+11+1+-2 +40

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

The area of the map is the product of the length and width. write and expression for the area as the product of the two binomials do not multiply
