Step-by-step explanation:
the shape is a trpizoid with height y
A=(a+b)/2 *h (a=2x=4cm, h=y=4cm, b=2z=12 cm
A=(4+12)/2 * 4
Area=16/2 *4=8*4= 32 cm²
Answer: 25
Step-by-step explanation: (x-a)² = x² - 2ax + a²
From x² - 10x + k we deduce that 10x = 2·5x and a = 5
Then k = 5²2
He drove 56 miles because if you divide 168 and 3 it equals 56.
