Answer:
a) x(x-2)
b) 6x(2x+2)
dont know c and d sorry
Step-by-step explanation:
2a^3-4a^2+5a+3
Explanation:
For standard form you always start with the one that has the biggest exponent to the least one
The angle bisector, median, and altitude are all the same things in an isosceles triangle.
That means that the legs of the smaller triangles created by the altitude are 4 root 2.
By special properties of an right triangle, the hypotenuse is 8.
Since the legs of the original right triangle are congruent, the area of the original triangle is 8*8/2.
Now we just simplify:
8*8/2=64/2=32
Area of a trapezoid is found with the formula, A=(a+b)/2 x h.
I would say the answer would be 105
