The total area of the the picture and frame is given by the equation A = (16 + 2x)(24 + 2x) = 384 + 32x + 48x + 4x^2 = 4x^2 + 80x^2 + 384
Sample answer from Edmentum
Answer:
D = (9.6,0). AC is horizontal with y=0 at all points on AC. Also, because BD is an altitude, it forms a right angle with AC, so BD is a vertical line. For all points on BD, x= 9.6.
Hope this helps, have a good day (:
Answer:
Its a right angle triangle so trigonometry is used.
a is the hypotenuse, b is the adjacent.
Use sin to find a. Use tan to find b.
A triangles measure = 180
45 + 35 + x = 180
80 + x = 180
x = 100
Hope this helps!
The 2nd one is the answer because it shows Distributive Property which is a(b+c) or <span>(b+c)a.</span>
