Can you please give a clearer explanation of what is your question?
Step-by-step explanation:
Answer:
d. 7 × (10 + 9) = (7 × 10) + (7 × 9)
Step-by-step explanation:
The format of writing numbers in distributive property is a(b+c) = (a×b)+(a×c)
We can see that in choice d. 7 × (10 + 9) = (7 × 10) + (7 × 9) it is in correct format of writing numbers in distributive property. Thus, choice d. is correct.
Verification:-
a(b+c) = (a×b)+(a×c)
7 × (10 + 9) = (7 × 10) + (7 × 9)
Answer:
See below
Step-by-step explanation:
<u>Sine function</u> would be easiest
in a right triangle sin = opposite leg / hypotenuse
sin 57 = 10.8 / x
then <u> x = 10.8 / sin 57 </u> then <u>x = 12.88 units</u>
