Answer:
Everything should simplify down to -9a-3 (your answer)
Step-by-step explanation:
Distributive property is basically <em>multiplying the outside number into the inside</em> parenthesis (). Basically #(a)--->#a or #(a+b)---> #a+#b
Since you're not ask to solve for anything but simplify, just multiply 3 to -3a and -1.....
so 3*-3a is -9a and 3*-1 is -3 and you have 3(-3a-1)= -9a-3
24(10,000)+11(1,000)
=240,000+11,000
=251,000
U have posted 6 & 7 instead so let me answer them instead ..as for 6 you must use Pythagoras theorem ..

Lib _ _ _ P. So u can see they form a right angled triangle. by pythagoras ,answer would be 4 .
Similarly draw a rough diagram for 2nd one u will get the answer as √495 foot ..
The lowest value of the range of the function would be -2, as this is the lowest the y value goes
Answer:
1. 4x
2. 3x+9
3. 8x-21
Step-by-step explanation:
1. Combine like terms (3x)+(2x)(-x)
2. 3(x+3)
3x+9
3. 6x-3+2(x-9)
6x-3+2x-18
6x-3+2x-18
6x-21+2x
6x-21+2x
8x-21
