11/7+12/5=55/35+84/35=139/35
Answer:
The area is 5 units²
Step-by-step explanation:
∵ The area of the square of side length 3 which contains
the quadrilateral ABCD = 3 × 3 = 9 units²
∵ The area of the 4 triangles on the sides of the quadrilateral ABCD
= 1/2(2)(1) + 1/2(1)(2) + 1/2(2)(1) + 1/2(1)(2) = 4 units²
∴ The area of quadrilateral ABCD = 9 - 4 = 5 units²

80t3
Step-by-step explanation:
80t^3
Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.
80t^3
Answer:
- y +4 = (-1/6)(x -9)
- y = -1/6x -2.5
Step-by-step explanation:
The point-slope form of the equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
For your given values m=-1/6 and (h, k) = (9, -4), your equation is ...
y +4 = (-1/6)(x -9)
__
Solving for y puts this in slope-intercept form.
y = -1/6x +9/6 -4 . . . . eliminate parentheses, subtract 4
y = -1/6x -2.5
