What is the area of the composite figure? assume angles that appear perpendicular are perpendicular and lines appearing parallel are parallel.

Area = 130.5 square units

Step-by-step explanation:

Split the figures into 3 shapes (triangle, rectangle and triangle)

Area of triangle on the left: A = 1/2(3)(3) = 4.5

Area of triangle on the right: A = 1/2(6)(6) = 9

Area of the rectangle:  A = (13)(9) = 117

Area of the figures = 117 + 9 + 4.5 = 130.5 square units

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
