The perimeter is the total of the length • 2, + Width • 2. Doing it in reverse order, 230 - 2(Width) = 104.
104/2 = 52
Answer:
Step-by-step explanation:
The total amount of flour, in cups, Matthew needs is equal to 
. Because he only has 4 cups, we can write the following expression to determine how many additional cups of flour he needs:
It is: 5.61 times 0.15 = 0.8415
Answer:
3x+1/2x
Step-by-step explanation:
When simplifying algebraic expressions, we should first factorise each term fully to find any common factors. First we should factorise the numerator where 3x2-8x-3 factorises to (3x+1)(x-3). Next, we should factorise the denominator where 2x2-6x factorises to 2x(x-3). Now we see that (x-3) is the highest common factor of both the numerator and denominator, hence we can "cancel" the (x-3) term from both the numerator and denominator. Therefore, the expression simplifies fully to (3x+1)/(2x)
