Answer:
26 y + 5
Step-by-step explanation:
Simplify the following:
7 3 y + 4 3 y - 3 y - 2 2 y + 5
7×3 = 21:
21 y + 4 3 y - 3 y - 2 2 y + 5
-2×2 = -4:
21 y + 4 3 y - 3 y + -4 y + 5
4×3 = 12:
21 y + 12 y - 3 y - 4 y + 5
Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:
(21 y - 4 y + 12 y - 3 y) + 5
21 y - 4 y + 12 y - 3 y = 26 y:
Answer: 26 y + 5
D. 12 + 13 = 25,
Why you ask? Because the inverse operation of addition is subtraction.
Hope this Helps!!!
For the answer to the question above, I'll show my solution on how you can solve your problem.
AC² + BC² = AB²
<span>5² + 12² = AB² </span>
<span>25 + 144 = AB² </span>
<span>169 = AB² </span>
<span>13 = AB </span>
<span>Triangle ABC is proportional to triangle ADB. </span>
<span><u>AC </u>= <u>AB </u></span>
<span>AB AD </span>
<span><u>5</u> = <u>13 </u></span>
<span>13 AD </span>
<span>5AD = 169 </span>
<span>AD = 169/5 </span>
<span>AD = 33.8 </span>
<span>AD = AC + CD </span>
<span>33.8 = 5 + CD
</span>So the answer is
<span>CD = 28.8 </span>
25%... so yea it's just 25/100 that's 1/4 which is 25%
