Answer: 5x+4+2
Step-by-step explanation:
5x-1(-4+2)
multiply the -1 by the -4 and 2
5x+4+2
Answer:
Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height.
From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1)
Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula
Step-by-step explanation:
Y<1-6x
Insert the values of
