Answer:
c) 2x+1
Step-by-step explanation:
Let's x be number of Nick's goals.
Emma has scored 1 more than twice the number of Nicks.
1 more is +1, of twices the number is 2x.
so 2x+1=15

Answer:
On this case n =6 and x =6 we got:
Step-by-step explanation:
The utility for the combination formula is in order to find the number of ways to order a set of elements
For this case we want to find the following expression:
And the general formula for combination is given by:
On this case n =6 and x =6 we got:
Answer:
Step-by-step explanation:
Applying BODMAS here;
We first solve what is in the brackets:
9x - 81 -3 = -8x - 16
We then put the like terms together:
9x + 8x = -16 + 81 + 3
We then do the addition:
17x = -16 + 84
We then do the subtraction:
17x = 68
Simplifying this gives:
x = 
= 4
Answer:
The actual park has 0.7776 square meters
Step-by-step explanation:
To solve this we first have to find the value of the scale
We know that the width of the model is 8cm and that of the true park is 72cm², so if we divide 72 by 8 we will obtain the value of the scale
72 / 8 = 9
To find out how much the park area has, the park first we have to multiply 96cm² by the scale
As the scale of 9 is made for width and length, when we calculate the area it will be multiplied 2 times by 9, so to calculate the real area we have to multiply it 2 times
96cm² * 9 * 9 = 7776cm²
if we want the result in square meters we simply have to divide the result by 100²
7776cm²/100² = 7776cm² / 10,000
0.7776m²
The actual park has 0.7776 square meters
