Answer:
The price of a medium pizza with 3 toppings is $15.
Step-by-step explanation:
If "t" represents the number of toppings, you will use the expression "9+2t" and plug in 3 for t (since there are 3 toppings)
So it will look like:
9+2(3)
Then you're gonna use PEMDAS, multiply 2*3
9+6
And then you get an answer of $15
Hope this helps :))
Answer: 72
If a square has equal sides, each one of them are the same.
So if just two are 18cm then the others are too.
18 times 18 times 18 times 18 (18 times 4)
I would say sum because you are adding and it is 11r^3+11
Answer:
<em>41.8°, 138.2° and 401.8°</em>
Step-by-step explanation:
Given the expression;
Let P = sinx
The expression becomes;
3P²+4P - 4 = 0
Factorize
3P²+6P-2P - 4 = 0
3P(P+2)-2(P+2) = 0
3P-2 = 0 and P+2 = 0
P = 2/3 and -2
When P = 2/3
sinx = 2/3
x = arcsin 2/3
x = arcsin 0.6667
x = 41.8 degrees
Also if P = -2
sinx = -2
x = arcsin (-2)
x will not exist in this case
To get other values of x
sin is positive in the second quadrant
x = 180 - 41.8
x = 138.2°
x = 360+41.8
x = 401.8°
<em>Hence the values of x within the interval are 41.8°, 138.2° and 401.8°</em>
