Hello!
This question is an example of function notation. Function notation is basically f(x) , said as "f of x". To solve this problem, you need to substitute x = 2 into each x-value in this equation. F(2) is written as function notation, while x = 2 is not.
F(2) = 4x² - 3x + 5
F(2) = 4(2)² - 3(2) + 5
F(2) = 4(4) - 6 + 5
F(2) = 16 - 6 + 5
F(2) = 15
Therefore, the value of F(2) is 15.
Answer: 36 hotdogs
Step-by-step explanation: You need to find the least common multiple of 9 and 12.
You can check by multiplying 9 and 12 by consecutive whole numbers until you find a number that they match.
Example:
9*1= 9 , 9*2=18, 9*3= 27, 9*4=36, 9*5=45
12*1=12, 12*2=24, 12*3 =36
They both share 36.
Answer:
0.0009
Step-by-step explanation:
Given:
square shape
Perimeter 28 feet
Find its area
A square has 4 equal sides, so perimeter is 4a
Perimeter = 4a
28 ft = 4 a
28 ft / 4 = a
7 = a
One side of the the square is 7 ft.
Area of a square is the measure of one side raised to the power of 2.
A = a²
A = (7 ft)²
A = 49 ft²
Answer: 75
15 multiplied by 5 (how many times it takes 20 to get to 100) gives us 75 :)
