Step-by-step explanation:
simplify the equation
5-x(2)-3x(4x-7)/(5-x)(3x)
=10-2x-12x²+21x/15x-3x²
=-12x²-23x+10/15x-3x³
the answer is B
yes, Robot is correct but Irum is not
Answer: D
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
The grid lines are 1 unit apart, so you can determine the dimensions of the trapezoid by counting grid squares. The parallel bases have lengths 6 and 2. They are 5 units apart.
The area is given by ...
A = 1/2(b1 +b2)h
A = 1/2(6 +2)(5) = 20
The area of the trapezoid is 20 square units.
