2. ### jacque has a mirror. it was 1.2 m by 80 cm, he surrounds it with a border 8cm wide, what is the total area of the mirror and border?

Ok, so, you could see that once you add 8, you have 88 and 10.2, then you have a rectangle, with border 8 inches. So, you have a 8x8 square in each corner. Then 2, 80x2 rectangles on the top and bottom+ 2, 2x120 on each side, so if you add it up it would be 8x120+8x120+8x8+8x8+80x8+80x8=10176cm^2

5. ### the area of a rectangle is 344 cm. The height is three more than five times the base.Wat is the height?

a = lw 344 = (5w+3)(w) 344 = 5w^2 + 3w 5w^2 + 3w - 344 = 0 This will not factor, so you must use the quadratic formula to solve. x = -b +- sqrt(b^2 - 4ac)/2a x = -3 +- sqrt(3^2 - 4(5)(-344))/2(5) x = -3 +- sqrt(9 - -6880)/10 x = -3 +- sqrt(6889)/10 x = (-3 +- 83)/10 x = 80/10, x = -86/10 x = 8, x = -8.6 So now we have the roots, and...
