Answer:
216 marbles bought altogether
Step-by-step explanation:
small m- 10
large m- 8
10×12+8×12=
120+96
= 216
Answer:
A. The amount per text message.
B. 16x x y = 3.20
Step-by-step explanation:
A. the amount per text message doesn't change, only the amount of times you message does.
B. (below)
X- The amount of messages sent.
Y- The amount of months.
There is a trig identity called the sum of 2 angles for sin its<span>
sin(a+b)=sin(a)cos(b)+cos(a)(sin(b)
</span>
You will need to use it. So in your question split the 4x in 2 equal parts 2x and 2x
<span>
</span><span>sin(4x)=sin(2x+2x)
</span>Now using the expansion above you will get
<span>sin(2x+2x)=sin(2x)×cos(2x)+cos(2x)×sin(2x)
</span>And it will simplify to
<span><span>2sin(2x)cos(2x)
I hope this helps you! Good luck :)</span></span>
The notation in its current form isn't entirely clear.
Did you mean to write 
? The 4 isn't in the square root.
If so, then the expression is in simplest form because we cannot simplify 
any further (note how 10 doesn't have any perfect square factors other than 1).
Also, the 3/4 portion is fully reduced already.
------------------------
Or,
Did you mean to write 
? This time the 4 is inside the square root.
If so, then we can simplify like this
This means that
