A) 4x + 12

B) 16x + 48

C) Yes.

Step-by-step explanation:

For part A, the distributive property is when you multiply all the numbers in the parentheses by the number that is right next to the parentheses. So, the equation would become; 4x + 12.

For part B, you just double everything by multiplying it by 2. So instead of 4(x + 3) it would be 8(2x + 6). So, now we do the distributive property again and we come out with 16x + 48.

For part C, it is correct because x has also been multiplied by 2, so if none of the numbers change, it would be exactly the same. I hope this helps. Please mark me brainliest!

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
