Answer:
9×17
Step-by-step explanation:
because 17 is greater than 10.
2y= 2x - 10 is the correct answer
25% because 21 is a quarter of 84. And 21 times 4= 84, so 21 is 25% of 84.
Answer:
see in the picture, the perimeter of this rectangle is
2( x + 3x) = 8x but the perimeter is 65.6
=> 8x = 65.6
<=> x = 65.6/8
=> x = 8.2
