Try calculating each of these yourself:
<span>First, 34(58 + 9) = 34(67) = 2278 </span>
<span>A. 34 x 67 = 2278 </span>
<span>B. 58(34 + 9) = 58(43) = 2494 </span>
<span>C. 34 x 58 + 34 x 9 = 34 x (58 + 9) = 34 * 67 = 2278 </span>
<span>D. 1,972 </span>
<span>So the answer is B and D are not equal to 34(58 + 9).

Answer:
Kim is 16 years old and her sister is 8 years old.
Step-by-step explanation:
We can use equations to represent this scenario.
Let Kim's age be 'k' and her sister's age be 's'.
Thus, k=2s (since Kim's age is double of her sister)
and k+s=24 (their ages add to 24 (from question)
Substituting the first equation:
2s+s=24
3s=24
s=8
Therefore, Kim's sister is 8 years old.
Now substitute this value into the second equation:
k+8=24
k=16
Therefore, Kim is 16 years old.

Answer:
<em>h=</em> 10m
Step-by-step explanation:
<em>1/2x12x18.2=109.2m squared</em>
<em>then u divide it by 21.8</em>
<em>109.2m2/21.8m/ 1/2=10m</em>
<em>h=10m</em>
