4. Let the dimensions of a rectangle be (4 x (871209)5 + 3 x 49762105) ft. by (7 x (871209)3 - (49762105)4) ft. Determine the area of the rectangle. (Hint: You do not need to expand all the powers.)

Find the least common multiple of the expressions: 1. 3x^2, 6x - 18 2. 5x, 5x(x +2) 3. x^2 - 9, x + 3 4. x^2 - 3x - 10, x + 2 explain if possible

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte

The area of each triangle is 7 square units. the surface area of the triangular prism is
