Verified answer

|-4| = 4

|18| = 18

4 + 18 = 22

|-4| + |18| = 22

l -- 4 l + l 18 l = 4 + 18 = 22

| –4 | + | 18 |

= 4 + 18

= 22

3x-4y=4 x+2y=18 From the 2nd equation, we are able to rearrange to get x = 18 - 2y substitute x = 18 -2y into the 1st equation: 3(18- 2y) - 4y = 4 fifty 4 - 6y - 4y = 4 Rearrange and assemble like words: 50 = 10y y = 5 on the grounds that y = 5, plugging y =5 into any of the two equations (enable's do the 2nd equation): x + 2(5) = 18 x + 10 = 18 x = 8 Now, on the grounds that we've x = 8 and y = 5, we are able to sub that into x^2+y^2+xy (8)^2 + (5)^2 + 8*5 = sixty 4 + 25 + 40 = 129 wish this facilitates!

WOOO BASIC MATH

ok u take the absolute value of -4 witch is 4 and 18 is 18 so u add 4+18=22

I -4 I means the absolute value of -4.....Absolute value is how much any number is from 0. So, -4 is 4 units away from 0. So, the absolut value of -4 is 4.

So, the absolut value of 18 would be 18 because it is 18 units away from 0.

So, 4 + 18= 22

22 is your answer

| - 4 | + | 18 | = 4 + 18 = 22

Ans: 22

I-4I=4

make a number line. it will really help...all this is is how many places the number is away from zero so -4 is 4 places away from zero so you change it to 4 and 18 is 18 places from zero so it stays.

so 4+18=22

|-4|+|18|

First you would get the absolute value or the numbers or spaces away a number is from zero.

|-4|=4

|18|=18

Then just add them.

4+18=22

22

because its basically 4+18
