Answer:

CD is to DE as CB is to BA

4 is to 6 as 3 is to y

1.5 is to 3 as 3 is to 4.5

AC = AB + BC

AC = AB + 3

Since AB = 4.5 then AC = 7.5

The answer is C

D is the correct answer, first you have to write to you equations 1+ the absolute value of 2+ X equals nine and 1+ the absolute value of 2+ X equals -9 then you must subtract one from both sides

Find the error and explain why its wrong
UNO [17]

Answer:

The last part.

Step-by-step explanation:

The error is only at the last part. Basically the answer part.

The answer should be —

13 \sqrt{5}

We don't multiply the square roots when adding or subtracting. That'd contradict the rules.

Here, we let the square root of five as x-term.

\sqrt{5}  = x

4 \sqrt{5}  + 9 \sqrt{5}  = 4x + 9x

As we add up, we would get 13x. Thrn we convert x-term back to square root of five.

The answer would be —

13x \\ x =  \sqrt{5}  \\ 13 \sqrt{5}

Remember that we don't multiply the square roots when adding or subtracting.
